Finally got to do something that I have meant to do since we moved in more than a year ago. I replaced the worn out extension springs with a single torsion spring. I got a couple of bids when we first moved in and the prices seemed outrageous. Eventually I stumbled across a kit sold by Menards to convert to a torsion setup from extension springs.
Went from this:
To this:
Another reason I've wanted to do this is that the end of the track made it impossible to install a door on one of my upper cabinets.
Now that the extension springs were out of the way, the support could be moved and extra track cut off.
Still a close fit with the door track. About 1/8" to spare.
Also decided to shorten up the other side to make it match. Had to resist painting the supports while I had them off. Still need to repair the ceiling where the supports were mounted.
