LiftMaster CSW24UL Commercial Swing Gate Operator with Battery Backup
The LiftMaster CSW24UL (replaces the older CSW24VDC and CSW24U) is a 24VDC continuous-duty commercial swing gate operator built for high-traffic sites — gated communities, commercial complexes, industrial premises and large residential properties.
Battery backup is included, so the gate keeps working through a power cut. The non-scissor swing arm reduces entrapment risk compared with scissor designs.
Level gates only. The CSW24UL must be installed on a gate that swings level. It cannot be used where the gate rises over a slope. UL325 compliant to the August 2018 revision, which requires monitored secondary entrapment devices — the LMRRU photo eye is included.
