LiftMaster CSL24UL Commercial Slide Gate Operator

Battery-Backed Continuous-Duty Automation for Commercial Slide Gates

The LiftMaster CSL24UL Commercial Slide Gate Operator is a 24 VDC continuous-duty system designed for high-traffic residential, commercial, industrial, and restricted-access vehicular entrances. It handles slide gates weighing up to 1,500 lb and traveling up to 50 ft, with a gate speed of approximately 12 inches per second.

The CSL24UL combines a 24 VDC motor with soft start and soft stop, a 10:1 wormgear reducer operating in a synthetic oil bath, electronic limits, inherent obstruction sensing, and integrated battery backup. Two 12V 7Ah batteries are included, allowing the gate to continue operating when AC power is unavailable. The system accepts 120 or 240 VAC single-phase power and is also compatible with solar installations using the appropriate LiftMaster solar equipment.

For access management, the CSL24UL supports myQ technology for remote monitoring and gate control when paired with compatible LiftMaster connectivity equipment. Security+ 2.0 radio, wireless dual-gate communication, PosiLock, programmable auxiliary relays, loop detector inputs, Quick Close, Anti-Tailgate, and monitored safety inputs provide flexibility for commercial perimeter access applications.

Conclusion

The LiftMaster CSL24UL combines continuous-duty commercial slide gate performance with battery backup, solar capability, myQ connectivity, PosiLock, and flexible access-control integration. Its 1,500 lb capacity, 50 ft travel range, and included 30 ft chain make it well suited to gated communities, commercial properties, industrial facilities, and other high-use perimeter entrances.

The included LMRRUL photoeye and 5 ft monitored edge provide important entrapment protection components, but they should not be assumed to satisfy every installation by themselves. LiftMaster requires monitored protection in both the open and close directions, and each gate site must be evaluated for all entrapment zones and any additional monitored devices required.
