12" radius on Tall door?

[bralyman]

I'm putting a 11 x 12 garage door in a barn. There could be a small clearance problem as the 12' tall door comes to the next truss that is about 11' 6" back from the door. If I put in a 12" radius track it will be OK. A 15" radius may need to drop down some to clear under the truss. Will the door pull up that much easier with a 15" radius compares to 12"? I may or may not get an opener.

I'd call the door MFG and ask them what they think.

12" is fine i think.
