A jackshaft or wall mount garage door opener costs $450 to $800 installed in New York. It mounts on the wall beside the door and drives the torsion bar directly, so it needs almost no ceiling clearance. In low headroom garages it is frequently the only opener that will physically fit.
A jackshaft opener does away with the ceiling rail entirely. It bolts to the wall next to the door and turns the torsion bar directly, which frees the whole ceiling and needs only a few inches of headroom above the door.
In this region that is not a luxury feature, it is a solution to a very common problem. Under-house garages in Bay Ridge, Marine Park, New Dorp and Sheepshead Bay routinely lack the clearance for a standard rail, and so do many of the converted garages in Levittown.
It requires a torsion spring system rather than extension springs, and it needs the door to be properly balanced, because it drives the bar directly. On a door that is out of balance it will complain immediately, which is arguably a feature.
What it is good at
- Needs almost no headroom, so it fits where nothing else will
- Frees the entire garage ceiling for storage
- Quiet, since there is no rail above your head
- Usually includes an integrated deadbolt lock on the door
What it is bad at
- Costs more than any rail-mounted drive
- Requires a torsion spring system, not extension springs
- Requires a well-balanced door, and will not tolerate a bad one
- Not every door and track configuration suits one
Jackshaft questions
How much headroom does a standard opener need?
A standard rail opener typically needs around twelve to fourteen inches above the door, and low-profile kits get that down to about eight. Below that, a wall mounted jackshaft is the answer.
Can I fit a jackshaft to any door?
It needs a torsion spring system and a door that is correctly balanced. If your door runs on extension springs, converting to torsion is part of the job and it is priced separately rather than hidden in the total.
