Thank you for this very descriptive door installation and adjustments video. After 17 years of the door to my utility shed being "Hot" and snapping up if you did not control the ascent, the proper spring tension has now been applied. The door comes just off of the door plate when all of the way down and then released. It is very easy to lift without having to control it.

Might I suggest that you include a link to the PDF installation file into your additional information about the video.

What is the long piece of rubber for?

Can a motor be added to the 650 series?
