Hi All I have just finished raising up the roller door 4 inches so instead of the roll hanging down passed the Dorr opening it now is up clear.
I had to do this so our new caravan can run inside without ripping off the door. I did one side at a time so the spring tension was not lost, by using a piece of heavy gauge steel channel as packing piece which sat on top of the support brackets that were already there. I had to drill holes in the bottom to take bolts and holes in the top to take the U bolts. I pulled down the door so the weight was taken off the roll and it was easier to lift. I used a combination square to measure the distance from the vertical support to the side of the axle so I could placed it back exactly where it was before. I sprayed the brackets with cold galvanising spray paint so they would not go rusty. I was pleased that the spring tension was not lost and the door works successfully after altering its original position. Ray [Non-text portions of this message have been removed]
