Accentra (Formerly Yale) 50-1178-0001 (1178L) Replacement Spindle

Accentra (Formerly Yale) 50-1178-0001 (1178L) Replacement Spindle

The Accentra 50-1178-0001 (technical part number 1178L) is a genuine OEM Replacement Spindle designed specifically for the 8800 and 8800FL (Fairfield) Series Mortise Locks. This spindle serves as the critical drive shaft, transmitting rotational force from the lever handle to the internal hubs of the mortise lock case to retract the latchbolt. Precision-cut for the industry-standard 1-3/4" door thickness, this spindle is the factory-spec solution for repairing worn, twisted, or snapped lever drives in both legacy Yale and modern Accentra installations.

Institutional Grade Features

• 8800 & 8800FL Series Integration: Engineered specifically for Accentra’s heavy-duty 8800 series mortise locks, ensuring the correct timing and engagement with the internal locking hubs.
  
• Optimized for Standard Doors: Factory-sized for 1-3/4" (44mm) thick doors, eliminating the need for field cutting and ensuring a perfect flush fit with the trim.
  
• High-Torque Durability: Manufactured from hardened steel to withstand the high rotational stress and daily "levered" force typical of schools, hospitals, and office buildings.
• Direct OEM Replacement: Restores the crisp, responsive feel of the lever handle, eliminating the "loose" or "slipping" handle movement caused by rounded or fatigued legacy spindles.
• Brand Compatibility: Fully compatible with all Yale-branded 8800/8800FL series mortise locks, facilitating a seamless transition to the Accentra brand.
