LiftMaster SL3000501UL Slide Gate Operator - 1/2 HP

Continuous-Duty Slide Gate Operator for High-Traffic Vehicular Access

The LiftMaster SL3000501UL is the 1/2 HP single-phase model in the SL3000UL commercial slide gate operator family. Designed for vehicular slide gates in residential, commercial, industrial, and restricted-access applications, it is rated for gates up to 1,000 lb. and 50 ft. long, with a maximum gate travel distance of 52 ft.

Built for high-cycle perimeter access, the SL3000501UL uses a continuous-duty AC motor with Class H insulation and a 30:1 worm gear reducer in a synthetic oil bath. The steel chassis, UV-resistant polyethylene cover, and mechanical limit system make it suited for permanent outdoor slide gate installations where consistent operation and serviceability matter.

The control system supports myQ remote monitoring and operation, Security+ 2.0 remote access, wireless dual-gate communication, quick close, anti-tailgate programming, timer-to-close, auxiliary relay control, and LED diagnostic troubleshooting. For access-controlled entrances, it can be integrated with compatible keypads, telephone entry systems, loop detectors, card readers, maglocks, warning devices, and remote controls.

This operator includes a LiftMaster LMRRUL monitored retro-reflective photo eye and a 5 ft. edge sensor kit for close-direction entrapment protection. Additional monitored open-direction protection is required and must be selected based on the gate layout and identified entrapment zones. For wireless edge installations, the LMWEKITU wireless edge kit is available separately.
