LiftMaster K80-9001 Feather Key — Approved Slide-Gate Drive Service

The LiftMaster K80-9001 is the feather-key service reference listed in documented industrial slide-gate operator repair information, including the SL585UL arrangement. It is a mechanical drive component for the specified keyed connection, separate from a lock key, complete shaft or sprocket assembly. Match the actual shaft and hub callout and obtain the approved key dimensions before ordering. Select the replacement by the complete part number and the installed equipment configuration. A similar photograph or a shared LiftMaster brand name does not establish interchangeability. Confirm the applicable service drawing before ordering so the repair addresses the correct component and its related mounting, connection and operating requirements.

Compatibility — Models, Versions and Exclusions

Identify the Assembly and Plan the Repair

Inspect the keyed shaft and mating component before selecting a feather-key-only repair. Wear in either keyway can prevent a new key from restoring the intended connection. Record the precise service location and component markings and obtain the complete dimensional specification instead of transferring measurements from another LiftMaster key.

The feather-key name does not establish a complete retaining package or permission to modify the keyways. Follow the manufacturer’s approved fitting and retention method for the actual drive. Have qualified personnel secure the gate and isolate the equipment before mechanical service, restore alignment and guarding and verify the operator’s required operating and protection functions after repair.

Compare the replacement with the installed service arrangement before dismantling the equipment. Photograph the part’s location and record the complete model and visible service numbers. Inspect the surrounding attachment points and mating components for wear, impact damage or misalignment. Replacing one worn item will not correct a damaged support or another component that continues to impose abnormal loads on the repaired assembly.

Package Contents and Separate Requirements

This offer identifies the feather-key service component. Confirm current quantity and complete dimensional requirements. A shaft, hub, pulley, sprocket, retaining hardware, complete drive assembly and operator are not established as included. Select separately worn mating components after checking the cause and extent of keyway damage.

Safety Warnings — Read Before Installation or Service

• WARNING: A moving gate and exposed feather key — approved slide-gate drive service can cause serious injury. Installation and service require a qualified gate-systems technician.
• Isolate AC power, batteries and any solar supply as applicable, and secure the gate against unexpected movement before work begins.
• Keep people clear of the gate and drive during supervised testing. Never bypass required entrapment-protection devices or increase force to overcome a mechanical fault.
• Restore all covers and guards, then verify travel endpoints, reversal and every required safety device before returning the gate to normal operation.

Related Products and Important Differences

• LMRRUL monitored photo eye — a separate protection option only where the exact operator and control revision approve it; not a universal legacy retrofit.
• LMWEKITU monitored wireless edge kit — a separate edge communication system for approved controls and resistive edges; not a replacement for this mechanical or electrical service part.
