Liftmaster 041A6550, SCREW DRIVE RAIL CLIPS KIT
The LiftMaster 041A6550 is a screw drive rail clips kit used to organize and retain wiring along compatible garage door opener rail assemblies. These clips help keep wall-control or sensor-related wiring neat and out of the path of moving parts. Missing or broken clips can leave wires dangling, rubbing against the rail, or getting pulled during opener service.
This is a small hardware and wire-management service kit, not a drive repair kit. It does not replace the rail bracket, trolley, screw coupling, or drive rack. Compatibility is tied to the rail profile and opener generation, so the parts diagram should be checked before ordering.

Technician Note
If the original clips are missing, inspect the wiring for damaged insulation, pinch marks, or loose staples before installing new clips. Wire should be routed so it cannot contact the moving trolley or screw drive parts.
Before Ordering
- Confirm the opener rail profile and parts diagram
- Check for 041A6550, 41A6550, or 28A143 references
- Inspect existing wiring for damage before re-clipping it
- Verify this is the clip kit needed, not a rail bracket or trolley part
- Do not route wires where they can contact moving parts
Important Ordering Warnings
Rail clips help manage wiring but do not repair damaged wiring. Replace damaged low-voltage wire rather than simply clipping it back in place.
Professional Advisory
If wiring has been cut, pinched, or overheated, have the opener wiring checked before returning the system to service.
