Another John formulated on Thursday :
- Thanks to breaking the clamps TWICE...

I can't see how you can break the plastic clamps, at least on mine. If
it tries to close onto anything, the door just unrolls itself around
the axial into bigger loops. I did though manage to break one of them
during installation and it was a simple job to install a replacement,
they just hook on and slide into place.

Well mine breaks 'em: it just continues unrolling (even though it's
being stopped by the obstruction), and this process seems to break the
clamps. (I'm trying to think this through, but nothin' happens [in my
head]). The guy who fitted it, and came back to fix the new clamps,
wasn't surprised at all by this happening, and had indeed given me
severe warnings against propping things up near the door, when he first
installed it.


The motor has a built in adjustable over load system,

Don't think mine has that.

a top stop and
bottom stop adjustments - both very precise and have never needed any
further adjustment.

Mine has that: in fact this is the only method of determining when to
stop rolling down, or rolling up.


The control unit includes a couple of adjustable
timers, for up and down. You just adjust them each, to allow just
enough time for the door to fully open and fully close.

No timers.


I was quite impressed with the kit, especially for what I paid for it.

Ah yes: "kit" -- you were confident enough to look for a kit, and then
install it yourself, and so you know all about yours! I on the other
hand "paid a guy to do it" (once again, lack of DIY balls on my part!)

Which brings me to my final point: what is the make of yours Harry?
Mine seems to be made by Autoroll UK. (And in fairness to them: I'm
perfectly happy with the door, within its limitations, which were
explained to me when it was installed. It's an economy door.)
