Liftmaster Jackshaft Garage
Door Opener Model 3800

Chamberlain's Liftmaster Jackshaft Garage Door Opener Model 3800 mounts on the wall so you have no overhead clutter taking up ceiling space.

Liftmaster's Jackshaft Garage Door Opener mounts on the wall at either side of your garage door. This unit attaches to the torsion bar above your garage door. If you have very low, cathedral or an obstructed ceiling, this is one that will solve your clearance problems.

Torsion bar drive means no chain, belt, or screw. A 24 Volt DC motor with soft start and soft stop provides you ultra quiet operation. If you have a bedroom above the garage this model is your ideal choice.

Add on the optional EverCharge^TM Battery Backup system and stop worrying about the inconvenience of power outages. While your neighbors have to get out of the car in the rain or snow you just push the button on your remote and your garage door opens with the power of your battery backup system.

The model 3800 is designed for use on sectional doors only, up to 14 feet high or 180 square feet

Installation Features:

• Wall-mount installation - left or right side of door. No rails to hang. Unit requires an electrical outlet within 6 feet

• Push button limit settings - Auto-force automatic force sensing feature constantly monitors garage door system and adjusts forces to temperature fluctuations, floor height and door track movement

An enclosed gear casing means you never have to lubricate gears as continuous lubrication provides longer life and dependability.

Once your door closes the included power lock engages just like a deadbolt ensuring your door cannot be forced open.
