Compact & perfect for a garage with a low ceiling. The smaller size means you think you have less power, yet that isn’t the case. Much lifting force is lost between the motor and the garage door with chain and belt drive systems. A screw-drive opener is more efficient in power transfer. A similar-sized screw-drive opener can lift more in weight than a chain drive opener that’s a similar size.
The quietest of all the openers is the screw-drive garage door opener. There’s no chain clanking around & it doesn’t get squeaky like some chain drive openers. The transfer of power is efficient, lifting movements are smoother & don’t create noise-generating pulls & jerks. If you leave home early in the morning or come home late from work, the noise level with a screw-drive garage door opener is perfect for you.
