We ran into a problem in the installation process due to the construction of the shop.
The inside truss wasn't spaced far enough away from our track so it interfered with the max height the door would raise, only allowing the 12" high door to raise to 10'9", but we found a solution and solved the issue for the customer. Allowing them the full 12" high clearance. They were satisfied and happy with the end result!
Another job well done.
