This slide gate motor has been recently upgraded by Liftmaster to be UL325 Compliant. This means that it is mandatory for the operator to have at least two functioning SAFETY DEVICES.

PLEASE NOTE: If you order this product you will receive the newly updated UL325 Model which will include an upgraded control board, a pair of Photo Eyes (Model LMRRUL / hoods included), and A 5’ Resistive Safety Edge (Model S505AL). No additional charges will apply.

It is recommended you add Liftmaster Wireless Receiver & Transmitter Kit (LMWEKITU) for convenience and/or to minimize complications involving the wire from the included Safety Edge. These accessories are available in the product options below.
