LiftMaster Industrial Slide Operators
LiftMaster industrial slide gate operators are 24VDC brushless units for heavy and continuous-duty slide gates up to 5,500 lb, with myQ remote monitoring.
About LiftMaster Industrial Slide Operators
For industrial and high-traffic commercial slide gates, LiftMaster offers three brushless DC operators in 14-gauge steel all-weather cabinets with locking doors. Each includes a Security+ 2.0 3-channel receiver for up to 50 remotes, four programmable auxiliary relays, myQ remote monitoring and access-control integration.
The INSL24UL handles gates to 2,200 lb and 70 ft with continuous duty, battery backup, soft start/stop and a manual disconnect, and it offers a retrofit option for SL585 and SL595 operators. The HDSL24UL handles 3,000 lb and 75 ft at a variable 0.5-1 ft/sec, ships with an LMRRUL photo eye and S505AL 5 ft edge, and can sync two gates. The IHSL24UL covers gates to 5,500 lb and 90 ft. Quick Close helps prevent tailgating.
These operators are UL 325 listed, and external entrapment protection is required. For a quote, send gate weight, length, daily traffic and whether you are replacing an SL585 or SL595.
