LiftMaster CSL24UL Commercial Grade Slide Gate Operator

Continuous-Duty DC Motor w/ myQ for Commercial and Residential Gates

The LiftMaster CSL24UL is a 24V DC continuous-duty slide gate operator built for high-traffic commercial, industrial, and residential vehicular gate applications across UL 325 and UL 991 Class I through IV. It handles slide gates up to 1,500 lbs and 50 ft at 12 inches per second. The CSL24UL ships as a complete kit with everything needed for installation and immediate operation, including two 12V 7AH batteries, LMRRUL monitored retro-reflective photoeye, 5 ft. edge sensor kit, 30 ft. #41 black oxide chain, eye bolt kit, cover, and hardware. The 10:1 worm gear reducer operates in a synthetic oil bath with soft start and soft stop on every cycle. The 1/4 in black powder-coated steel chassis provides corrosion resistance, and the high-density UV-resistant polycarbonate 2-piece cover protects internal components in outdoor installations.

The CSL24UL includes the Security+ 2.0 3-channel on-board radio receiver, compatible with up to 50 remote controls (unlimited with model 811LMX or 813LMX). myQ technology enables remote monitoring and gate control from anywhere via the myQ app. PosiLock automatically powers the operator and returns the gate to the closed position when pushed off the closed limit. Wireless dual-gate communication synchronizes bi-parting gate operation without conduit runs or driveway cuts. The operator is Fire Department compliant, opening automatically upon loss of AC power or battery depletion. Anti-tailgate and quick close capabilities are programmable, and HomeLink version 4 and higher is supported.
