LiftMaster K80-36931 Hardware Kit for LA350 Swing Gate Operators
The LiftMaster K80-36931 hardware kit supports LA350 swing gate operator service where the original fasteners or mounting hardware need replacement. Hardware on a swing gate operator works under repetitive load, vibration, and outdoor exposure, so using the correct kit helps maintain the intended bracket alignment and mechanical strength of the installation.
This kit is closely related to the LA350 bracket and mounting system. It should be ordered only for LA350 applications that call for K80-36931, especially when replacing brackets, servicing the arm mounting points, or correcting missing original hardware. Do not assume this hardware will fit LA400, LA412, LA500, or other swing operator families.

Technician Note
When hardware loosens repeatedly, look for bracket misalignment, gate sag, missing stops, or operator over-travel. Replacing the hardware without correcting the cause may lead to another failure.
Before Ordering Checklist
- Confirm the operator model is LA350
- Compare the old hardware to the kit components
- Inspect brackets, gate frame, and post before reassembly
- Confirm the gate moves freely by hand when disconnected
- Do not mix hardware from different swing operator models
Professional Advisory
After hardware replacement, verify that the gate travels smoothly and all safety devices are operating. A qualified technician should reset limits and force settings when mounting geometry has changed.
