12x12 Commercial Installation 

This video is all over the place. Skipping a lot of steps. I guess if you have done this for years it would make sense but if this is for training purposes it is very confusing.

That spring change would suck with that operator mounted to the center bearing plate

use some grease on the axle of your running wheel then the door will run much nicer

Inch and a half gap from the roller to top fixture.... lol

Your basically saying “I’ve done the best I can but, I need to move on because this is taking too long” I have 12x12 full glass doors and they are balanced perfectly and have no issues. I also installed them myself as a first timer. Your going to burn that motor out in a year or two Edit….your just pushing product. That’s not $12 I need to spend. That door is loud as shit for a first time door install

I have an 18x7 commercial door, is kinda heavy to lift, at midway it's balanced, and after the that, it wants to slingshot open. Then it's hard to pull down to close, again, until midpoint, then wants to slam down.

Really dude? Like really???

You should hire a professional production company and remake this video.

Yeah I'd delete this video and try it again if I were you.
