My son's latest problem is that his house came with a large roller
shutter garage door which has been bodge-repaired in the past but which
needs further work.
The roller is oct(or more)agonal that has a full-length fitting
consisting of a rod on to which have been threaded hanger clips that
expose themselves another short piece of separate rod that the hanging
straps for the shutter clip onto. This all forms a sort of hinged
T-piece that clips onto the top of the shutter and when the roller rolls
the straps bend and the shutter rolls up over them. After a lot of
bending, the straps break.

Because the whole assembly is up near the roof of the big double garage,
access is very limited and nothing can be threaded on or off the ends.

Spares are unobtainable, but he has found some longer straps that can be
cut down and clipped round the exposed rod with the whole thing in situ.
The problem then is how to weld or glue the clips together so they can't
come off the exposed rod. They are sort of P-clips.

He has found some clips that will hold temporarily, but the original
clips were obviously spot-welded to make them secure. Neither he or I
can weld, and this is all above head, badly lit and in a real pain of a
place. He has been asking me about small nuts and bolts, and I have been
suggesting epoxy, but I don't think either are very good.
Each existing assembly is finished off with a sort of filament-loaded
parcel type sticky tape, which we think we have identified.

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!)

Probably best to start again with a new door.
Folding panel doors are cheaper but not as secure.
Easier to DIY as they are not as heavy and come in parts.

I have a "Garador".
You can get insulated ones too, almost totally draught proof.

Bill was thinking very hard :

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.

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.

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.

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

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

Many thanks for this. I have passed the suggestions on. Said son has
been out of the country, so I will look at it with him when he is back
home.

The door is heavy, but I'm not sure how freely it moves. As well as the
electric motor it has a handle to wind it up and down and I've once had
to raise it manually. Never again.
