LiftMaster MA033 Hardware kit for articulating arm only
The LiftMaster MA033 is the hardware kit used to install or service compatible LiftMaster articulating barrier arm assemblies. Articulating arms are used when a standard straight barrier arm cannot clear the site because of a low ceiling, parking garage structure, canopy, overhead obstruction, or other clearance limitation. The hardware provides the pivoting and mounting pieces needed for the articulating arm setup, but it is not the arm itself.
This kit should be matched to the exact arm and operator configuration. Public references identify MA033 for MA024 and MA034 style articulating arms, including MA024-10 references in some listings. It is commonly associated with LiftMaster barrier gate operator applications, including Mega Arm / Mega Arm Tower style lanes where the correct arm assembly is already specified. Arm length, breakaway behavior, clearance, and operator balance all matter, so verify the parts diagram before ordering.

Technician Note
MA033 should be ordered only after confirming the arm model. Articulating arms have different geometry and mounting requirements than straight barrier arms, so substitutions can create clearance and balance problems.
Before Ordering Checklist
- Confirm the existing or planned articulating arm model: MA024, MA024-10, or MA034.
- Verify the barrier gate operator model and arm length.
- Check overhead clearance and site layout before choosing an articulating arm.
- Confirm whether the arm itself is needed; MA033 is hardware only.
- Do not mix straight-arm and articulating-arm hardware unless the LiftMaster parts diagram supports it.
Professional Advisory
Barrier arm hardware affects movement, balance, and safe vehicle-lane operation. A qualified gate technician should install and test articulating arm hardware after any service work.
Product Q&A
Does MA033 include the articulating arm?
No. MA033 is the hardware kit only; the articulating arm is sold separately.
Which arm models are commonly associated with MA033?
Public references commonly list MA033 with MA024, MA024-10, and MA034 articulating arm applications.
Can MA033 be used on a straight barrier arm?
No. It is intended for articulating arm hardware applications, not standard straight arm hardware.
Why use an articulating barrier arm?
Articulating arms are used where overhead clearance prevents use of a full straight arm.
What should be verified before ordering?
Verify the arm model, barrier operator, lane layout, overhead clearance, and LiftMaster parts diagram.
