The Schlage 47279023 is the OEM L9000 HSLR Screw Pack for the L Series High Security Ligature Resistant (HSLR) mortise lock, documented in the Schlage L Series Service Manual. The pack contains five ferrules, two spindles, and ten #8-32 security Torx screws. The security Torx screws are T15 size, confirmed in the Schlage L9000 Series HSLR Installation Instructions (doc P519-054): "Two drivers to fit T15 security Torx bits" are listed as required tools for every HSLR installation.

This pack is the field replacement and service hardware for the HSLR trim assembly. Standard Schlage L Series fasteners and generic hardware cannot substitute for any component in the 47279023 pack - each item is specific to the HSLR installation and its ligature-resistant, tamper-resistant design requirements.

What HSLR Means on the Schlage L9000 Mortise Lock

HSLR stands for High Security Ligature Resistant. The Schlage L9000 HSLR is the highest level of ligature-resistant hardware in the Schlage L Series catalog, designed specifically for behavioral health facilities, correctional facilities, and any high-risk institutional application where both physical security and ligature hazard mitigation are required on the same door.

The official Schlage HSLR product documentation describes it as using a "patented crescent-style handle design" that has become the standard for ligature resistance and accessibility in healthcare environments. The HSLR trim achieves the "Paperclip Protection" designation as determined by NYS-OMH (New York State Office of Mental Health) testing, enabling its use in low, medium, and high-risk areas. The system is ADA compliant and meets the "no pinch, no grasp" requirement. It is available only in 630 Satin Stainless finish. The HSLR mortise chassis is ANSI/BHMA A156.13 Series 1000, Grade 1 certified and UL listed for 3-hour fire doors.

Schlage Screw Pack: What Each Component in the 47279023 Does

Ferrules (5 included): Ferrules are metal collars that fit around mounting posts or spindles at the trim-to-door interface. In the HSLR installation, ferrules close any potential gap between the trim plate and the door face. Gaps at this location can function as ligature anchor points even when the handle profile itself is ligature-resistant. The ferrules are part of the complete HSLR design system that eliminates all attachment opportunities across the full trim assembly.

Spindles (2 included): Spindles connect the inside and outside levers through the door to the lock chassis. HSLR spindles have a specific profile that mates with the crescent handle drive interface. The Schlage L9000 HSLR Installation Instructions document the spindle as a separately installed field component: "Install spindle and then spring cage." Two spindles in the pack accommodate both spindle positions in the lock or replacement across two units.

#8-32 Security Torx Screws, T15 (10 included): This is the critical anti-tamper component of the HSLR installation. Standard T15 Torx screws can be removed with any T15 driver bit available at any hardware store. Security Torx screws have a center post inside the drive recess that prevents standard Torx bits from seating. Only a security Torx driver (with the matching center void) can drive or remove these screws. In a behavioral health or correctional facility, this means occupants or patients cannot remove the trim with any commonly obtainable tool.

Schlage L Series Mortise Lock Parts: Why HSLR Hardware Cannot Be Substituted

Standard Schlage L Series installation hardware uses Phillips or standard hex screws. Using standard screws in an HSLR installation, even temporarily during a service call, compromises the tamper resistance of the entire installation. Any standard Phillips or Torx screw in an HSLR trim makes the hardware removable with tools widely available to facility occupants. The 47279023 screw pack ensures every replacement service call on an HSLR L9000 mortise lock restores the full security Torx fastening system as originally specified.
