Opener Type	Description
*Belt Drive*	Belt drive garage door openers offer ultra-quiet, long lasting performance. The fiber-reinforced belt eliminates noise associated with chain and screw drive openers. The direct current (dc) motor operates smoothly and quietly. This unit slows down for starts and stops. The security codes for the controllers automatically change each time the system is activated and never repeats. This prevents would-be intruders from gaining access to your code. The belt drive is considered to be the best opener available.
Screw Drive	Screw drive garage door opener uses a lifting mechanism that moves along a threaded steel rod. They are powerful units and because they have few moving parts, they require the least maintenance. This is generally the slowest moving of the three types of openers and is not as quiet as the belt drive units. However, the latest screw drive models feature a plastic lined track which increases opening speed while reducing the noise level associated with metal to metal contact.
Chain Drive	Chain drive garage door openers use a metal chain to guide the door up and down along its tracks. Chain drive systems are the most common and usually the least expensive. They are the noisiest of the three types of openers because they use a metal chain along a metal trolley in order to guide your garage door.
