Garage Door Rail Extensions

[OldracerJones]

Need some help finding a subject again. My shop doors, 3 ea 12 w x 10 h have standard insulated garage doors with the rails that go horizontal at top of door. Want to save space and send the rails up the 3/12 pitch roofline then use a Liftmaster to raise and lower. Garage door guys told me you can't have the rails follow the ceiling and use a liftmaster. At one time, I found an old post on this forum that showed a company that sold all kinds of extensions. Anyone remember that sight? Anyone know if what I want to do is doable?

Don't need an extensio n to follow a roof pitch, but you do need a new set of springs...

Should be able to use your Liftmasters as well.

Oh, and plan to upgrade the hinges (rollers and centers) between the bottom and 1st intermediate...

When you pitch the door, suddenly those take a lot more load and tend to bend - you'll want some 11ga hinges there for long term reliability...

Thanks, the links were what I was looking for.

You can definitely use 3800 jackshaft operators with 3/12 pitch. You may need to use rollers with ball bearings and spring pushers to keep the cables from throwing off the drums... but you can definitely do it!
