LiftMaster MA005C Slip Clutch Option, Mega Arm Gearbox

Designed to protect barrier arm systems from sudden impacts and overloads, the LiftMaster MA005C Slip Clutch option delivers dependable torque-limiting protection for Mega Arm gearboxes. As a purpose-built slip clutch (Manufacturer Part Number MA005C) it slips under excess load to absorb shock, preventing gearbox gear stripping and reducing replacement costs. Installing this slip clutch option reduces downtime and service calls, extending the life of your barrier arms and improving uptime for access control and parking operations.

The MA005C integrates seamlessly with LiftMaster Mega Arm gearbox assemblies and is ideal for high-traffic sites where safety and continuous operation matter—such as gated communities, commercial parking, and perimeter security installations. By minimizing mechanical stress, it helps maintain reliable operation for surveillance and monitoring equipment that depends on consistent barrier performance. For integrators and facilities managers seeking to lower maintenance expenses and increase system resilience, the MA005C is a cost-effective upgrade.
