Replacement Q104 Arm Assembly for LiftMaster Swing Gate Operators
The standard arm assembly is a critical mechanical connection between the operator and gate. During operation, this assembly transfers rotational movement from the operator to the gate leaf, allowing the gate to move through its opening and closing cycle.
If an existing arm becomes bent, worn at the pivot points, damaged or improperly aligned, replacement may be necessary to restore the mechanical connection between the operator and gate.
When replacing the LiftMaster 75-50293, installers should also inspect the gate hinges, mounting brackets, physical stops, operator mounting geometry and gate alignment. Mechanical problems elsewhere in the installation can place unnecessary stress on the replacement arm.
