quote from the worlds largest manufacturer of door openers.

“Each garage door opener has its advantages. The chain drive and belt drive are good in all applications, and the screw drive is best used on one piece doors that tilt rather than go up on a track. The screw drive runs a little slower than the other two garage door openers.

The belt drive is the quietest garage door opener and would be recommended for garages that have a room above them.

The chain drive is the garage door opener that we have been making the longest and offers dependable performance year after year. All of our garage door openers are very reliable and require virtually no maintenance”.
