The Model LJ8900W is a jackshaft door opener, as manufactured by The Chamberlain Group, Inc. and is for use on light-duty commercial standard, vertical and high lift sectional doors with torsion assemblies. It is rated up to 10 cycles per hour during peak periods. It features a compact design ideal for limited height, cathedral, or obstructed ceiling installations.
Project an invisible light beam across the garage door opening and automatically reverse the door if anything interrupts the beam while the door is going down. Sensing technology will stop the door from closing if contact is made with a person or object. Opener light turns on automatically when The Protector System's infrared beam is broken.
Security+ 2.0 rolling code technology assures a new code is sent every time the remote control is used.
Specifically designed to maintain accurate tension and eliminate "cable throw", which occurs when the cable slips off the drum.
