Liftmaster K75-50120, RELEASE ARM KIT
The LiftMaster K75-50120 is a Q060 release arm replacement kit used on select LiftMaster commercial swing gate operators. The release arm is part of the manual release or drive disengagement hardware that allows service access and controlled release of the operator mechanism.
A bent, broken, missing, or badly worn release arm can make the operator difficult to disengage or re-engage. This kit is most often associated with CSW200 and CSW24V style swing gate operators, but the exact release hardware should be confirmed from the operator parts diagram because older Elite and LiftMaster parts can share similar names.

Technician Note
If the release arm is damaged, inspect the clutch, release linkage, shaft, key, and gate load. Excessive force needed to release the operator may indicate a deeper mechanical problem.
Before Ordering
- Confirm K75-50120 or Q060 in the operator parts diagram
- Check the operator model and generation
- Inspect the clutch/release hardware for bent or seized parts
- Confirm the gate can move manually when released
- Do not force the release arm if the gate is under load
Professional Advisory
A manual release should work smoothly and safely. If the gate is heavy, out of balance, or binding, secure the gate before servicing the release mechanism.
