H-style operators include a floor level chain hoist to ease manual operation in an emergency or power outage.
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.
With the addition of the 828LM MyQ technology enables the user to monitor and control their operator and light with their smartphone tablet or computer.
Alerts can be received as email or pop-up (push) notifications on a mobile device ensuring the status of your commercial door.
Security+ 2.0™ safeguards your facility – with every click a new code is sent to the commercial door operator so the door opens only for you.
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.
LiftMaster has created Trolley Service Kit K75-39337 with all the necessary parts and provides instructions on how to replace a damaged travel nut
