Choosing Your Garage Door Opener Drive System
Belt Drive Garage Door Openers - use a rubber drive belt to move your garage door as reliably as any chain drive opener, but much more quietly. Belt drive openers generally cost a bit more than chain drive or screw drive openers, but they are definitely worth the investment if your garage is attached to your home, and especially if you have a room over the garage.
Chain Drive Garage Door Openers - use a metal drive chain to reliably operate your garage door. Chain drive models generally cost less than belt drive or screw drive openers, but traditionally chain drive openers have always been relatively noisy during operation. This may be a welcome feature if you like to be aware of everyone entering or leaving your home, and it really doesn't matter if your garage is not attached to your home.
Screw Drive Garage Door Openers - rotate a helically threaded steel rod to operate your garage door. In terms of price and operational noise, screw drive garage door openers are typically considered to be intermediate between belt drive and chain drive models, and with fewer moving parts they offer smooth operation with virtually zero maintenance.
The Chamberlain LiftMaster 3800 Jackshaft Garage Door Opener is a unique wall-mounted direct drive unit that was specifically designed for installation in garages that don't allow for a traditional ceiling-mounted garage door opener, such as those with cathedral ceilings, oversized doors, or when you simply don't have enough room.
