Liftmaster Jackshaft Std Duty No Spkt incl
The Liftmaster JDC7S4BMC is a next-generation standard duty Jackshaft (non-hoisted) DC commercial door operator from the MAXUM Series. It is designed for sectional or rolling doors and is intended for use in NEMA 1 applications. Jackshaft operators are preferred over trolley operators in installations where overhead space is at a premium.
This model supports doors weighing up to 700 lbs, operates on 480Vac 3PH power, and delivers 1/2 HP equivalent horsepower rated as standard duty for up to 90 cycles a day. It accommodates a maximum door height of up to 40 ft. with up to a 10 ft. high lift. A 4.5 Ah battery backup kit is included as standard, and the unit comes with a monitored entrapment protection device (CPS-U) that is packed in.
This SKU is supplied without a sprocket. A sprocket is required for installation of each JDC operator and must be selected separately based on door weight and type to safely achieve recommended door speed.
