Knowing what features you want or power requirements to operate your garage door can be somewhat overwhelming. So whether you are looking at Marantec, or LiftMaster lets break it down.
The belt-drive system is the quietest drive type because its operation is the smoothest. The steel-belt is made to last and is strong enough to lift the heaviest garage doors. It's the perfect choice for replacing a noisy opener or the satisfaction of buying quality with a new garage door.
The chain-drive system uses a metal chain to lift the door. Chain drive systems are cheaper and most common, but they are inherently nosier, however they continue to be very popular. Just like there close cousin the belt-drive they are designed to lift even the heaviest carriage house garage doors. They are rugged, reliable, and deliver when called upon.
The screw-drive system uses a threaded steel rod to lift the door. The lifting force of these openers are superior and reliable, giving you years of operation. They requiring very little maintenance which is a definite plus.
The direct-drive mounts to the garage door shaft off to the side and operates much quieter than other openers; it is simply beautiful. Usually direct-drive units are used for low ceilings or obstructions but I see this technology being used in any situation.
