Liftmaster Jackshaft Hoist Ext Duty No Spkt incl

This is a next-generation MAXUM Series extended-duty Jackshaft (hoisted) DC commercial door operator from LiftMaster. It supports sectional or rolling doors weighing up to 1200 lbs in NEMA 1 applications and is rated for extended-duty use of up to 150 cycles per day. It operates on 480Vac 3-phase power and delivers the equivalent of 3/4 HP.

As a hoist-style operator, it includes a hand chain for manual door movement, making it well suited to facilities where reliable, frequent door operation is required. Jackshaft operators are preferred over trolley units in applications where overhead space is at a premium. The unit is battery backup capable and comes standard with a monitored entrapment protection device (CPS-U).

This operator is designed for commercial facilities running medium-to-heavy sectional or rolling doors at higher daily cycle counts. Note that a sprocket is required for installation and is not included with this configuration; the appropriate sprocket should be selected based on door type and weight.
