Compatibility and Cross-References
K081C0275, 081C0275 and 81C275 identify the same replacement-part reference. LiftMaster specifically lists models 3130 and 3240; other applications require confirmation through the opener’s parts diagram.
Verify the installed rail configuration and original rack before ordering. This listing is for the replacement rack, rather than a complete rail or opener.
Inspection and Installation
If the screw turns but the door does not move, inspect the rack engagement, trolley connection and drive components before deciding which part needs replacement. Disconnect opener power before service, follow the model-specific installation instructions, and test travel and safety reversal after reassembly.
