    Default Acrow props

    G'day all,
    despite spending most of yesterday googling with no luck, I was hoping I could call upon your collective wisdom to answer a couple of question for me please?
    I want to lower the mounting brackets for a roller door in my shed to give me more clearance above the roll.
    Can I use acrow props to both support the ends of the roller door with some appropriate bracing? And secondly, can I use the acrow to lower the roller door into the new position (about 60mm)?
    Thanks for looking,
    Steve.

    Yes you can, I used 4 Acrow props and 4 blokes to raise a shed 160mm. Before you move the door make sure you tie it up so it cant unroll, I have used rope.

    1. First get some of those straps for tying loads to trailers and straps up the roller door after it has been wound up.
    2. use acrow props if you want, to prop up one end. and slowly undo one end U-bolt, the spring will unwind which you will need to wind up later on.
    3. unscrew the bracket and lower it to the position you want.
    4. lower the prop onto the bracket. and secure U-bolt.
    5. You might want to secure one end before working on the other depending on whether the angle of the slant allows it.
    6. finally wind up the spring again using a pipe wrench while slackening the U-bolt momentarily.

    Thanks for the replies and hints, they're very appreciated.
    I had contemplated doing it as follows, please tell me if it wouldn't work or if I'm missing something.

    1. Prop and sure up both ends of door centre pipe.
    2. Remove one sliding track and cut it to size.
    3. Re-install that side track, using the stop at the top of the track to keep the bottom rail of the roller door in place at the lowered position.
    4. Re-position that side bracket to the appropriate height while still supporting the door pipe.
    5. Repeat steps 2 to 4 on the other side.
    6. Lower both side props gradually onto the brackets and secure.
    7. Re-tension the door spring.

    My thought that using the top stop on the sliding track would negate having to tie/strap the door up, I could be off the mark here completely.
    Thanks again for your help,
    Steve

    For safety sake tie the door roll up as the door could easily spring out of the guide with only one there.

    Do what he says, or you will have a mess on your hands.

    Thanks for the advice, I had a 'roller door moment' a while ago and I'm not keen to have another one (.
    Thanks again,
    Steve.

    60mm is not much so an acrow prop will have enough travel assuming you can start with the pin near the top of the slot.
    Acrows are quite unstable if used alone and the whole thing could end up a big mess on the floor if you don't brace properly.
    You will need to make sure the door can't fall off the top of the props and that the props can't fall in any direction.
