Hi all,

I am building an extension, and am pondering how to fix the door into
the door opening. Its a 300mm cavity wall, with a 90mm deep door frame
recessed by 50mm to match the doors on the rest of the house. A quick
diagram is he

Could you build the frame in as you go?
Then you could use these:

Screw end goes into the frame,and the other end is sandwiched into a mortar
joint.
No unsightly screw holes on the visible faces of the frame.

Thanks, Mark. I hadn't come across those before, and that looks like
an easy solution.
