Noise reduction: Jackshaft openers don’t have a belt so they are essentially silent. Additionally, because there is no motor rail along the ceiling of the garage, any nearby bedrooms or living spaces will not be disturbed, as is possible with other garage door openers.
Ideal for irregular garages: Jackshaft openers are great for homes that have high ceilings, where they’d have to extend the hang brackets for an overhead garage door opener. Additionally, if you have anything blocking the path of a standard garage door opener, a jackshaft opener can be a solution since it doesn’t have a motor rail.
