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
within an LA500 arm
Kit includes: MM-00031 wall L-bracket (1) MM-00032 trolley arm 105 degrees (1) MM-00033 trolley extension arm (1) MM-00034 trolley arm sliding bracket (1) MO-00004 trolley arm compression spring (1) and MR-00009 red rope c/w handle and warning label (2)
The MWT12 safety edge transmitter is designed to provide wireless signal transmission form the safety edge to the motor controls.
It is easily mounted and wired to the gate or door edge sensor. When the sensing edge comes into contact with an obstruction a closed circuit signal is created and is sent to the transmitter.
The transmitter relays the information to the receiver and the receiver passes the signal along to the operator motor.
The gate or door stops movement and will then reverse the direction of travel.
Comes standard with a NEMA 4 weather-proof enclosure. The enclosure can be easily mounted with the four mounting holes and screws provided
