Replacement Parts for the Brands Locksmiths Actually Use

When a Von Duprin 98/99 series pushbar fails or an LCN 4011 arm goes missing, downtime isn't an option. Security Parts stocks repair components for the commercial door hardware brands that drive the industry. Whether you're tracking down a specific latch assembly for a current installation or sourcing a component for an older series that's still in the field, our diagram-based lookup gets you to the right part number without the guesswork.

Von Duprin Exit Device Parts

98/99 · 33A · QEL · 2000

Von Duprin has been building exit devices since 1908, and their 98/99, 33A, QEL, and 2000 series panic hardware is installed in commercial buildings across North America. Finding the right replacement part used to mean flipping through a paper catalog or calling a distributor and hoping they had it. We stock Von Duprin components down to the chassis level, and our interactive diagrams show you exactly where each part sits in the assembly before you order.

Parts we stock for Von Duprin include 98/99 series latches, dogging keys, cylinders, outside pull handles, mount brackets, concealed vertical rod components, trim assemblies, and QEL motor cartridges.

If your series or model isn't listed, contact us at 845-935-0301 and we'll pull availability.

LCN Door Closer Parts

4011 · 4040XP · 1461 · 1260

LCN closers are in hospitals, schools, office towers, and retail chains everywhere. The 4011, 4040XP, 1461, and 1260 series all have their own specific replacement arms, covers, springs, and fluid-filled bodies. We stock LCN parts for both current production models and older series still in service. If you're rebuilding a closer or need a new arm bracket, our parts diagrams show the full exploded view so you can confirm the component before it ships.

Parts we stock for LCN include closer arms, cover plates, mounting brackets, shoe assemblies, spring covers, and replacement bodies for the 4040XP and 4011 series. We also carry parallel arm and regular arm configurations for the most common LCN series.

Schlage Lock Parts

B · L · ND · AL Series

Schlage holds a massive share of commercial hardware installations, from B-series cylindrical locks in office doors to L-series mortise locks in high-traffic institutional settings. Cylinder cores, chassis, levers, roses, and trim components all wear out with heavy use. We carry Schlage parts for cylindrical, mortise, and interconnect locksets — the kind of depth a locksmith or facility manager needs when a lock fails on a Friday afternoon and there's no time to wait a week on a distributor order.

Parts we stock for Schlage include cylinders, cores, lever trim, chassis, strike plates, and components for B-series, L-series, ND-series, and AL-series locksets.

If you're maintaining a large building with mixed Schlage inventory, contact us about volume availability.

Falcon Panic Hardware Parts

19 · 24 · MA Series

Falcon exit devices and panic hardware are widely installed across commercial and institutional buildings, and they hold up well when they're properly maintained. The 19 series, 24 series, and MA series cover everything from standard storefront applications to heavy-duty institutional installations. We carry Falcon components for exit devices, trims, and related hardware so you're not hunting through multiple suppliers to complete a single service call.

Parts we stock for Falcon include exit device latches, trims, cylinders, dogging components, and mounting hardware for the 19 and 24 series. Our diagram lookup covers Falcon models with exploded views so you can identify the exact component before ordering.

Who Orders Commercial Door Hardware Parts From Security Parts?

Working Professionals on the Job

Our customers are mostly working professionals. Locksmiths on service calls who need a specific component the same day. Facility managers at schools, hospitals, government buildings, and office complexes who maintain large door hardware inventories and can't afford to shut down an opening for a week waiting on a distributor. General contractors sourcing commercial door components for renovation and tenant improvement projects.

Dealers & Property Managers

We also supply independent hardware dealers who want a parts-focused supplier stocking down to the component level, and property management companies that handle their own maintenance and need a reliable source for Von Duprin, LCN, and Schlage parts without ordering full assemblies when all they need is a cylinder or a closer arm.

Frequently Asked Questions

How do I find the right replacement part for my model?

Use the Brand/Series/Model lookup tool at the top of the page. Select your brand, series, and model number to access a full parts diagram with labeled components and part numbers. Click any component to order it directly. If your model is not listed, call 845-935-0301.

Do you carry OEM replacement parts?

We stock both OEM and quality aftermarket components depending on the brand and part. Product listings specify the source. Contact us before ordering if you specifically need an OEM component and we will confirm availability.

What is the difference between an exit device and panic hardware?

Exit devices and panic hardware refer to the same category of hardware: devices that allow egress from a building by pressing a crossbar or touchpad. Panic hardware is the term used in building codes, while exit device is the standard trade term. Both are governed by UL 305 and applicable life safety codes.

Do you ship the same day?

Yes. Most in-stock orders placed before our daily cutoff ship the same day. Contact us at 845-935-0301 to confirm stock availability and cutoff time for time-sensitive orders.

Can I order individual parts or only full assemblies?

Individual components are our specialty. We stock latches, dogging keys, cylinders, closer arms, brackets, strike plates, and other components at the part level. You do not need to order a full assembly when only one part has failed.

What if I cannot find the part I am looking for?

Call 845-935-0301 or email sales@securityparts.com. We can often source parts that are not currently listed in the catalog, and we can help identify components from a model number or physical description.

Do you offer free shipping?

Free shipping applies automatically to all orders of $450 and over. Orders below that threshold are charged standard shipping rates at checkout.
