Liftmaster K10-8007M, ARM CLAMP
LiftMaster K10-8007M is a replacement arm clamp for compatible LiftMaster barrier gate operator arm assemblies. The clamp secures the gate arm at the hub/shaft area so the barrier arm remains properly held during opening and closing cycles.
This part is most commonly associated with LiftMaster BG770 industrial-duty barrier gate operator applications and the 15ALUMARM aluminum boom arm reference. It may also appear under related numbers such as 10-8007, 108007, and G108007 in supplier catalogs.
A worn, cracked, missing, or improperly tightened arm clamp can allow the barrier arm to shift, sag, or slip at the operator hub. Correct clamp fit is important for safe arm movement, proper stopping position, and reducing stress on the internal shaft and drive components.

Technician Note
If the barrier arm has slipped, also inspect the arm hub, shaft, fasteners, and boom arm for damage. Replacing only the clamp may not solve the issue if the hub or arm is worn.
Before Ordering Checklist
- Confirm the operator is BG770 or another compatible barrier gate model.
- Check the boom arm type and arm hub style.
- Verify K10-8007M, 10-8007, 108007, or G108007 in the parts breakdown.
- Confirm whether new fasteners are included.
- Inspect the arm for cracks or deformation before reinstalling.
Professional Advisory
Barrier gate arms can move quickly and create pinch or impact hazards. Secure the arm and disconnect power before service, and use a qualified technician for arm clamp or hub repairs.
Important Ordering Warnings
- Do not operate the barrier gate with a loose or cracked arm clamp.
- Do not replace the clamp without checking the arm hub and fasteners.
