LiftMaster MA010 Gate Arm Bracket for Mega Arm Barrier Gate Operators
The LiftMaster MA010 is the replacement gate arm bracket used in the arm mounting area of select Mega Arm barrier gate operators. This bracket holds the arm assembly in the correct position so the operator can raise and lower the arm with proper alignment. In a parking, community, apartment, or commercial entrance, the bracket can become damaged from repeated cycles, vehicle impact, loose arm hardware, or a previous improper repair.
MA010 is not the barrier arm itself and is not the complete drive assembly. It is one mechanical part in the Mega Arm arm-support system. When replacing this bracket, the technician should inspect the surrounding hardware carefully. A bent cam arm, damaged shear pin, worn gear reducer, stretched belt, or misaligned arm can cause the new bracket to wear prematurely or leave the barrier arm operating incorrectly.

Technician Note
A bent arm bracket can be a sign of a vehicle strike or arm impact. Do not just bolt on the new bracket without checking the shear pin, cam arm, arm hardware, and travel setup.
Before Ordering
- Confirm MA010 is listed on the operator parts breakdown
- Inspect the barrier arm for bends or cracks
- Check MA013 or MA0137 shear pin condition
- Check MA012 cam arm alignment and magnet condition
- Verify the bracket mounting area is not cracked or distorted
Professional Advisory
Barrier arm repairs should be performed with the arm secured and power disconnected properly. Do not stand in the arm travel path or bypass safety equipment during testing.
Product Questions & Answers
What does the MA010 bracket do?
The MA010 bracket supports the barrier arm assembly on compatible LiftMaster Mega Arm operators.
Is MA010 the complete gate arm?
No. MA010 is the arm bracket, not the full barrier arm, gate operator, or gear reducer assembly.
What should I inspect after a barrier arm impact?
Check the bracket, shear pin, cam arm, arm hardware, gear reducer, belt, pulleys, and travel adjustment before operating the gate.
Is MA010 used with MA013?
Yes, MA010 is commonly found near the MA013 shear pin area in Mega Arm service paths, but each part has a separate function.
Can MA010 fit both Mega Arm and Mega Arm Tower units?
It is commonly associated with Mega Arm and Mega Arm Tower service paths where the parts diagram lists MA010. Always verify by diagram and generation.
