LIFTMASTER GARAGE DOOR OPENERS
Liftmaster Garage Door Openers
LiftMaster is the number one brand of professionally installed residential garage door openers. They provide 3 main categories of door openers: chain drive, belt drive and direct drive.
Read on for more information.
Liftmaster Chain Drive Garage Openers
Operated by a chain similar to that of a bicycle chain, these types of garage door openers push or pull a trolley (also known as a carriage) that connects to a metal bar, called a J-arm, that is attached to the garage door. If your garage is situated under a bedroom, the noise generated by this metal-to-metal contact and vibration may be a disturbance. We recommend these types of openers for detached garages. However, newer chain-driven units with DC motors and softer start-and-stop technology are much quieter than older openers.
Liftmaster Belt Drive Garage Openers
Similar in design and function to chain-driven models, belt-driven openers utilize a reinforced belt to push or pull the carriage or trolley. In these kinds of models, the belts may be made from fiberglass, polyurethane, or steel-reinforced rubber. Also, belt-driven openers are just as reliable as chain-driven openers but operate much more quietly. Although they cost a bit more than chain-driven openers, belt-driven ones require less servicing because they don’t require grease or lubricant.
Liftmaster Direct Drive Garage Openers
Comprised of just one single component in the form of a motor, these kinds of openers are claimed to be the quietest of all garage door units. Developed and manufactured in Germany, direct-drive motors travel along a stationary chain that is embedded in an overhead rail as opposed to a trolley or carriage in other kinds of garage door openers. A J-arm is responsible for linking the moving motor to the door. Direct-drive garage door openers tend to cost about the same as belt-driven units and also come with lifetime warranties!
