Garage Door Stop Bolt or Tab

[Orestp]

Hi All - just had a high lift conversion done on my garage doors - my installer did not put a stop bolt or stop tab at the end of my new garage door tracks. When using the opener to open one of the doors, the top section of the door went past the end of the track, fell out the end of the track, and and flopped down onto my the roof of my car (which was raised up on on a 4 post lift).

That's what happened on one door. On the other, the installer could not get the jackshaft opener to work - so he left us with manually pushing the door up / pulling it down, until he could get a replacement logic board for the opener (about 14 days ago). The first time we manually lifted that door, we pushed it a bit to forcefully and the top section flew out the end of the track - since it's now high lift, 11 ft ceiling and 16 foot door, it was not easy to get the top section back into the track.

Is it standard practice to put some kind of stop - a bolt or a tab - at the end of the garage door track so that the door does not fly out the end of the track?

Uhh yeah man, those stop bolts keep things, much like what happened to you from happening. Call up the company and have them come out, also the reason your door came out of the tracks is too much spring tension and the opener over running its up limit.

You need these, leaf bumper springs. If you put stop bolts in the tracks, you'll beat the rollers out of the top panel the first time you open the door too far. These springs hit the door directly. I couldn't find a picture with them installed.

This is a common problem with high lift doors. Even a perfectly balanced door will glide upward under it's own momentum, so you'll need a pull rope, or something, to use it manually. It sounds like he may not be very competent if he left you using the doors this way, especially since the working one had it's up limit set way too high.
