Liftmaster K75-39337 Trolley Kit

Liftmaster K75-39337 Trolley Kit

Trolley nut replacement kit. For use with LiftMaster® Model LA500 swing gate operators. LiftMaster advises the travel nut replacement be conducted in a controlled environment such as on a bench in a workshop, due to its complexity and the opportunity of dirt/debris being trapped within the transmission of the arm.

Check the manual or replacement parts diagram for specific part information before ordering to ensure compatibility.
