Is anyone here expert on these doors, or does anyone have a creative
solution?

As Google has demolished Picasa, the following is my first attempt at
a replacement to put pictures up. Hopefully it will work and make the
question a bit clearer (doubtful!)

I suspect some small nuts and bolts, or even pop rivets might do the
job, in clamping the loose end of the P to the rest. My guess is that
those metal P's will have to flex a lot, every time the door is opened
and closed, in which case they will eventually snap.


I was going to suggest pop rivets, recognising their limitations. But
you can get steel ones, which are much stronger than the default alloy
ones. You need a proper lazy tongs to set them

A better idea might be something like seat belt material, if the door's
weight can be relied upon to not need to be pushed down by the strap.

That's an idea I like. Plenty of sizes on eBay.


Mine uses 4x series of rigid nylon, curved, hinged straps, 5x sections
to each, rather like a course flat chain which fits closely to the
roller. I managed to damage 1 of the 4, so now it works fine with just 3
straps.

As the door is closed, at fully closed, the nylon sections go over
centre, so as to lock the door down in the closed position.
