Building a conservatory, but I'm missing a part. Has anyone ever seen one of these?

Mr Haribo

I'm putting together a second hand conservatory, but I'm missing some of this range of specific parts. Can't find them anywhere, been to a few hardware places, pvc wholesalers and no one seems to have ever seen them.

The roof bars of the conservatory (on which the roof panels sit) bolt into these little aluminium trapezoidal tabs at the edge of the roof. The tabs slide up and down on an aluminium bar that sits on top of the windows.

I think the bolts are a 4 or a 5.

The small 'arms' on some of the tabs aren't strictly necessary on the roof configuration I'm putting up

According to one man-in-a-van I was talking to, this kind of system to secure the roof bars hasn't been used for about a decade. So no big shops even bother to carry them. I don't really know how true that is though.

Heres a few pictures of them next to an inch tape.





The side view. (This shows how they slide up and down the bar.)

I could probably make do without them, jerry-rig up something, but it would make the whole assembly a lot easier if I knew where to find more of these yokes.

A good fab shop could make them up for you but they wouldn't be cheap. If you're anywhere near Cork there are a few small places that do all sorts of stuff for the pharma plants unfortunately they are well used to charging €€€€€€.
I've had some luck with custom bike places making up pieces as well.
I'm sure you've already tried googling the manufacturers name for the parts, sometimes when retailers say you can't get something, it just means that no-ones importing them anymore but they could be all the rage in belgrade.
