The Liftmaster Model 3800 offers an ultra-quiet, space-saving,
wall-mounted design. It is specially designed for garages and unique
applications that don't allow for a traditional garage door opener, such as
garages with very low, cathedral or obstructed ceilings, and is designed for use
on sectional doors only, up to 14 feet high or 180 square feet.
The Liftmaster Model 3800 DC Motor Residential Jackshaft Opener meets
all UL325 requirements, and is part of the Elite Series, designed to exceed
expectations.
