Garage door guy told me I could move the track over a little bit so that's
what I did.
Had to drill new holes in the wood holding the track brackets to the front
wall.
Got plenty of clearance now.
One thing I noticed, There is no cable running through the springs that help
pull the door up.
I thought there were supposed to be safety cables running through the
springs in case a spring would break?
Is this not the case?
Thanks, Tony
