DC Motor Residential Jackshaft Opener –

Today’s garages go far beyond a place to merely park your car. So no matter if you want the extra storage space up above, have an oversized garage door, or even a cathedral ceiling, the LiftMaster® model 3800 Residential Jackshaft Opener is the perfectly engineered solution to fit your specific garage door opener requirements. It mounts easily on the wall beside the garage door, and comes with a remote 200-watt light that can be positioned anywhere in the garage. The optional Battery Backup – that continues to operate your opener even when the power goes out – makes it even more convenient.
