Hi all,

I've been searching high and low for such a thing,

What exactly?

Ahh if I stop my flow and read the title again I can see....

(helps to put it in the message as well)

but can't seem to
find any.

The stuff I'm looking for fits into a small (1-2mm wide) channel
that's moulded into the door frame.

Some where that supplies UPVC doors?

There are normally factory places that will supply doors only for DIY
fitting, I'd have thought they may well have it.
