Thank you! My garage door was so bad that the original bracket was peeled back and the entire garage door was hanging on by a thin sheet of metal strip held on by one screw. The reinforcement bracket you showed saved me from a potentially bad accident. It was so easy to fix and easy on the wallet too.

Thanks, helped a lot

Great job and video!,

Can't you just advance the trolley and then just reprogram the door movement? Instead of messing with the tension springs on the chain or whatever you did there?
