Questions & Answers

Will this work on a 9' door?

Asked by: beel
Yes. The opener has an adjustment feature that allows for doors that are not exactly 10' long. I installed one on a 9'-9" door the other day.

My drive unit is 154 inches from the garage door to the pulley on my motor, Do I need a 10 ft extender on my new unit?

My new door is 8ft. by 16 ft. but the hanging hardware is in center of my garage and the chain drive rail is approx. 154 inches long, what length rail do I need if I go to a belt drive unit? I'm going to someoneelse install it.
Asked by: John
The unit goes by the door height so an 8 foot unit is what is needed.

The installation was completed by Home Depots recommended contractor and went quickly.
