Definition
An opener that mounts on the wall beside the door and turns the torsion shaft directly, instead of hanging from the ceiling with a rail. Jackshaft openers free up overhead space for storage racks or car lifts, run very quietly, and are the go-to answer for garages with low or obstructed ceilings. Most include built-in battery backup and smart controls. They cost more than a ceiling-mount unit, but for cathedral-ceiling or high-lift garages they are often the only clean solution.
