What applications is the Von Duprin 22 Series designed for?

Employee entrances, parking garage stairwells, healthcare clinics, multi-family residential corridors, and retail back-of-house doors. It is the mid-traffic Grade 1 specification in the Von Duprin lineup, below the institutional 98/99 Series in specification depth. See the Von Duprin panic bar selection guide for help choosing the right series for your opening.

What is the difference between the 22 rim and 2227 SVR configurations?

The 22 rim device latches at a single frame-side strike and is used on single doors or paired doors with a center mullion. The 2227 SVR device uses top and bottom rods for three-point engagement on double door openings without a center post.

Are 22 Series center cases interchangeable with 2227 SVR center cases?

No. The 22 rim center case is part 109012. The 2227 SVR center case is part 109358. These are different components and cannot be swapped between configurations. See the Von Duprin 22 Series exit device parts guide for interactive model diagrams.

Why does the 22 Series dogging key stop working over time?

The dogging shaft hole (part 090040) is approximately 1/4 inch deep. Using a short 5/32-inch hex key that does not reach full depth rounds out the hex engagement over repeated use. Always use the long version of the 5/32-inch key, pressing the key fully into the shaft before turning.

What is the metal end cap kit for the 22 Series?

Von Duprin introduced the 900397 metal end cap kit in 2016, replacing the historically fragile plastic end cap with a metal version. The kit includes the end cap, bracket, and mounting screws. As of October 2014, the plastic cap alone is no longer sold separately.

Does the Von Duprin 22 Series support electrified access control?

Yes. QEL modular conversion adds quiet electric latch retraction. RX and LX options add monitoring switches. The ALK alarm kit converts the device to an alarmed exit. CON integrates the device into the Allegion Connect ecosystem. See the Von Duprin QEL vs MEL guide for full electrified option comparison.

Quick Answer

The Von Duprin 22 Series parts and applications catalog covers a practical, Grade 1 panic exit device for mid-traffic commercial openings. Here is what to know before ordering:

Two configurations: 22 rim device (single doors and paired doors with center mullion) and 2227 SVR (double doors without a center post, three-point engagement).
Center cases are not interchangeable: 22 rim uses part 109012. 2227 SVR uses part 109358. Confirming configuration before ordering is the most important step in 22 Series maintenance.
Dogging failure fix: Use the long 5/32-inch hex key. Short keys round out the 090040 dogging shaft because the hole is only approximately 1/4 inch deep.
End cap: The 900397 metal end cap kit (2016) permanently replaces the historically fragile plastic version.
Electrified options: QEL, RX, LX, RX2, ALK, and CON integrate the 22 Series into access control and alarm systems without replacing the device.
Fire-rated variants: The 22F (rim) and 2227F (SVR) carry UL fire exit hardware listing. These require a 4-3/8-inch minimum stile width and do not support dogging.

What the 22 Series Is Built For

The Von Duprin 22 Series parts and applications catalog covers a practical, cost-effective Grade 1 panic exit device built for mid-traffic commercial openings where the full institutional specification depth of the 98/99 Series is not required but code-compliant panic egress is. Employee entrances, parking garage stairwells, healthcare clinics, multi-family residential corridors, and back-of-house retail doors. The 22 Series carries ANSI/BHMA A156.3 Grade 1 certification (2014 edition), UL listing for both panic exit hardware and fire exit hardware, and a parts catalog that has remained largely consistent for decades, which means components ordered today apply correctly to 22 Series devices installed in the early 1990s.

Von Duprin developed the 22 Series as the value-tier Grade 1 exit device in its lineup. The designation "22" reflects its position in the Von Duprin family below the institutional 98/99 and above residential-grade hardware. It is the most widely installed panic device in mid-traffic commercial and multi-family applications across the US.

The device ships non-handed, meaning it can be installed on left-hand or right-hand swing doors without modification. It fits door stiles as narrow as 3-13/16 inches on standard non-fire-rated configurations and 4-3/8 inches on fire-rated configurations. Compatible door thicknesses are 1-3/4 inches and 2-1/4 inches for both wood and metal doors. Available in 36-inch (3') and 48-inch (4') lengths to suit standard commercial door widths.

The center case measures 4-1/4 inches by 1-3/8 inches by 2-3/8 inches (108 x 41 x 60 mm). The mechanism case measures 2 inches by 3-3/4 inches (51 x 95 mm). Push bar projection is 3-3/4 inches (95 mm) at neutral and 3 inches (76 mm) when depressed. The touchbar height is 39-13/16 inches (1011 mm) standard, and 39-11/16 inches (1008 mm) when used with a mullion.

Under IBC 1010.2.8, panic hardware is required on all egress doors in assembly occupancies with an occupant load exceeding 50 persons and in educational occupancies. Under NFPA 101 (Life Safety Code), fire exit hardware must be used on doors in the means of egress where the door serves a high-occupancy assembly or educational space. The 22 Series, with its UL fire exit hardware listing, satisfies both requirements on qualifying openings. For full fire-rated door assembly compliance requirements, see the commercial door fire rating guide and the NFPA 80 inspection guide.

Von Duprin 22 Series Configurations: Rim and Surface Vertical Rod

22 Rim Device

Von Duprin 299 rim/vertical rod top strike. View product page and order.

The rim configuration is the standard 22 Series device for single doors and paired doors with a center mullion. The latch bolt projects from the device body on the door face and engages the 299 rim strike mounted on the door frame. The device ships with the 299 strike in dull black finish, a 5/32-inch hex dogging key, and all mounting fasteners for both 1-3/4 inch and 2-1/4 inch door thicknesses. Optional sex nuts and bolts (SNB) are available for through-bolt mounting.

The device covers stock hollow metal doors with 161 door prep cutouts.

2227 Surface Vertical Rod Device

The 2227 is the surface vertical rod configuration of the 22 Series, used on double door openings without a center mullion. The top rod engages a strike at the door header, the bottom rod engages the floor or threshold, providing three-point engagement. The 2227 uses a separate center case (part 109358) from the rim device (part 109012). These cases are not interchangeable, and confirming the configuration before ordering a center case kit is the step that prevents the most common wrong-part order on 22 Series maintenance.

22F and 2227F: Fire-Rated Configurations

The 22F (rim) and 2227F (SVR) are the fire-rated variants of the 22 Series, carrying UL fire exit hardware listing in addition to the standard UL panic hardware listing. Fire-rated configurations require a minimum stile width of 4-3/8 inches and do not support hex key dogging. Dogging is specifically prohibited on fire-rated door assemblies under NFPA 80, because a dogged device cannot swing to the closed and latched position required for fire door compliance.

When ordering replacement parts for a 22F or 2227F device, confirm the fire-rated designation before selecting a center case or trim component. Some trim functions are not available on fire-rated configurations. For ANSI/BHMA grade and UL listing requirements across all commercial door hardware, see the ANSI/BHMA door hardware standards guide. For a full comparison of 22 Series vs other Von Duprin exit device series, see the Von Duprin exit device series comparison guide.

Trim Functions and Outside Hardware for the Von Duprin 22 Series

The 22 Series ships ready for multiple outside trim functions. Understanding the function suffix is what determines which outside trim component applies to the opening:

EO (Exit Only): No outside trim. The push bar operates egress from inside only. No outside entry function.
DT (Dummy Trim): Outside pull only, no locking function. Used on non-secured egress doors where an outside handle is needed for aesthetics.
NL (Night Latch): Key locks and unlocks the push bar from outside. The 230NL trim plate measures 3 inches wide by 12-1/16 inches high by 3/32 inches thick.
TP (Thumbpiece): Outside thumbpiece unlocks the push bar. Used where key access is not required but outside entry control is needed.
K (Knob): Outside knob trim. Economy application.
L (Lever): Outside lever trim. The 230L trim was redesigned in 2008, moving the cylinder from inside the lever to a position above the lever. Current 230L dimensions: 3 inches wide by 6-3/8 inches high, 15/16 inches thick.

The 230 Series is the full-size trim line for the 22 and 2227 devices. The 210 Series is the economy trim line. The 230L and 210L levers use a shear pin (3/16-inch diameter by 5/8-inch overall length) at the lever base, designed to break if the lever is forced. This protects the trim assembly from damage on high-abuse applications. Shear pins are stocked as individual replacement components.

Von Duprin 22 Series Parts That Require Most Replacement

Center Cases

Von Duprin 109012 22/22-F rim center case. View product page and order.

The 22 rim center case part 109012 has been in production for approximately 40 years. It replaces all non-fire-rated 22 Series rim center cases, which means any 22EO device with hex key dogging on the hinge-side cover plate uses this case. This backward compatibility is valuable for facilities maintaining 22 Series devices installed in the 1980s and 1990s.

The 2227 SVR center case part 109358 has been consistent for approximately 30 years and replaces all worn 2227 SVR center cases.

For part diagrams and interactive component identification across the full 22 Series parts catalog, see the Von Duprin 22 Series exit device parts guide.

Dogging Assembly

Von Duprin 090040 hex dogging shaft. View product page and order.

Hex key dogging is standard on all non-fire-rated 22 Series rim devices. The dogging assembly consists of three components that are commonly ordered individually or as a kit:

090040 Dogging Shaft: The piece the 5/32-inch hex key inserts into. Critical installation note: the hole depth is only approximately 1/4 inch. The long version of the 5/32-inch hex key must be used. Short keys do not reach the full depth of the shaft and round out the hex over time, which is the most common cause of dogging failure on 22 Series devices in the field.
090042 Dogging Adapter Spring: Locks the dogging adapter into the mounting bracket.
090043 Dogging Adapter: The housing the shaft and spring fit through.

For 22 Series devices manufactured before 1998, the old-style dogging shaft has a different dimensional profile. Part 050709 is the conversion kit that updates pre-1998 devices to current spec dogging components. The dogging assembly components 090040, 090042, and 090043 also apply to devices manufactured after 1998 across the 22, 33A, 35A, 98, and 99 Series. See the Von Duprin 22/33A/35A/55 series exit device parts guide for cross-series compatibility reference.

End Cap and Bracket

Von Duprin 900397 metal end cap kit. View product page and order.

The plastic end cap on the hinge side of the 22 Series device is historically the component most likely to fail on high-use applications. When the end cap breaks, the dogging cover plate slides off and the device loses weather and debris protection. In 2016, Von Duprin introduced the 900397 metal end cap kit, replacing the plastic end cap with a metal version. This kit includes the end cap, bracket, and mounting screws. The full end cap and bracket assembly 900981 is the replacement for broken plastic end cap and bracket combinations. As of October 2014, Von Duprin no longer sells the plastic cap only; the complete assembly ships in its place.

Push Bar Retrofit Kits

Push bar retrofit kits are available for 22 Series rim devices in both 3-foot (36-inch) and 4-foot (48-inch) configurations. These kits replace the push bar assembly without requiring a full device swap, which is the correct maintenance approach when the push bar itself is bent or damaged but the mechanism case is functional.

Additional Replacement Parts

Additional components regularly replaced on the Von Duprin 22 Series in the field include:

090039 latch return spring: The latch return spring controls the return of the latch bolt after retraction. On high-cycle applications, this spring fatigues before other components. Replace if the latch bolt is slow to return or fails to fully project after the push bar is released.
Shear pins (230L and 210L levers): Replaceable individually. Replace after any lever has been forced.
QM SVR Device Retrofit Kit: For 2227 SVR configurations, converts older surface vertical rod devices to current-generation specifications without a full device replacement.

For guidance on when to replace vs repair an exit device, see the commercial door hardware replacement and repair guide. For scheduled maintenance intervals, see the commercial door hardware maintenance checklist.

Finishes

22 Series devices and trim are available in: powder-coated aluminum (689), powder-coated dark bronze (695), powder-coated chrome (526), powder-coated matte black (622), SP28, and SP313. Finish must be specified when ordering most trim components.

Electrified Options for the Von Duprin 22 Series

The 22 Series was designed for mid-traffic openings, but its electrified options catalog supports meaningful access control integration:

RX (Request to Exit): A switch placed in the push bar sends a signal to the access control panel when the push bar is depressed. This monitors egress activity on the opening without controlling it.

LX (Latch Monitor Switch): Monitors the position of the latch bolt itself, signaling when the door is not properly latched.

RX2 (Double Pushpad Monitor): Covers both push bar and pushpad monitoring in a single device.

QEL (Quiet Electric Latch Retraction): A modular field-installable conversion that adds electric latch retraction to a mechanical 22 Series device. When an authorized credential is presented or a remote release signal is received, the latch retracts silently, allowing entry from the outside without a key.

ALK (Alarm Exit Kit): Converts the 22 Series device to an alarmed exit device. Powered by a standard 9-volt battery. Controlled by a mortise cylinder (not included with the kit). When the push bar is depressed, the alarm sounds.

CON (Allegion Connect): Integrates the device into the Allegion wireless ecosystem for remote monitoring and control.

The QM SVR Device Retrofit Kit is available for 2227 configurations, converting older surface vertical rod devices to current-generation specifications without a full device replacement.

For a detailed comparison of QEL quiet electric latch retraction vs MEL motor-driven electric latch retraction on Von Duprin devices, see the Von Duprin QEL vs MEL guide. For the full QEL conversion kit parts breakdown, see the Von Duprin QEL conversion kit parts guide. For integrating panic hardware with building access control systems, see the access control and commercial door hardware integration guide and the electric strike installation guide.

Sourcing Von Duprin 22 Series Parts at Security Parts

The 22 Series parts catalog is both consistent and generationally stable. This works in both directions. The center case part 109012 applies to a 22 Series device installed today and to one installed in 1985. The dogging assembly components 090040, 090042, and 090043 apply to devices manufactured after 1998 across the 22, 33A, 35A, 98, and 99 Series. That consistency means a technician can confirm compatibility by confirming the series and the manufacturing year rather than hunting for a discontinued part number.

Security Parts organizes the complete Von Duprin 22 Series parts and applications catalog by model, with interactive parts diagrams for the 22 rim device and the 2227 SVR device. The diagram on each model page shows every component in the assembly, allowing visual confirmation of the part before the order is placed. This is the step that prevents the 109012 rim center case from being ordered for a 2227 SVR device that requires the 109358.

For the full Von Duprin lineup beyond the 22 Series, the Von Duprin brand catalog and exit devices section cover every active series with the same model-specific parts organization. Same-day shipping on stocked components from US warehouses. Pre-order compatibility support at 845-935-0301.

For the complete Von Duprin parts catalog by series:

The Von Duprin 22 Series delivers Grade 1 panic exit performance for the broad middle tier of commercial, healthcare, multi-family, and retail applications where the full institutional specification of the 98/99 Series is not required. The rim and 2227 SVR configurations cover the full range of single and paired door openings. Center cases have been consistent for decades. The dogging shaft 090040 requires the long version of the 5/32-inch hex key. The metal end cap kit 900397 resolves the historically weak plastic end cap. And the electrified options catalog, from RX monitoring through QEL modular conversion, supports meaningful access control integration on any 22 Series opening. Sourcing replacement parts starts with confirming the configuration (rim vs SVR) and the manufacturing year, then navigating to the correct model page in the Von Duprin 22 Series parts and applications catalog at Security Parts where diagrams confirm every component before the order is placed.
