Compatibility depends on the complete operator and door-arm configuration. Confirm the operator model, existing arm design, hole pattern, required length, and associated hardware before ordering. Matching the appearance alone is insufficient.
This kit contains the straight-arm component and is not a complete commercial operator or complete trolley assembly. Reuse or replace connecting fasteners only as permitted by the applicable LiftMaster parts diagram and installation instructions.
Disconnect and lock out electrical power before servicing the operator. Secure the door against movement and have a qualified commercial-door technician complete the installation and adjustment. Test the door balance, travel limits, reversing system, and required entrapment-protection devices before returning the operator to service.
Order this LiftMaster straight door arm kit when your compatible BMT, MT, T, or GT commercial trolley operator calls for K75-10214 or one of its verified alternate numbers.
