The operators are typically mounted to the wall when used with larger sectional overhead doors with vertical or high lift and mounted to the wall or the front of the hood when used with rolling doors and grilles.
H operators are attached to the door jackshaft to indirectly drive the door.

The travel nut on LA500DC and LA500DCS gate operators may break when excessive force is applied to the gate such as being struck from a vehicle.
The travel nut can be identified as the white plastic nut that attaches to the internal lead screw of the arm.
The symptom of this problem is that the trolley assembly slides back and forth along the guide slots without mechanical restraint.
