hi, i've got an up and over "canopy" garage door with the cables disconnected. the cables and spindles look as though they are still intact, but the big spring over the top of the door is completely untensioned.
I am thinking that I will need to reconnect the cables with the door up, apply a bit of tension to the spring before tightening the grub screws to re-engage the spring connection to the spindles.
Question is how much tension and how to apply it?
Any advice gratefully received.
