Frame fixings are long screws inside long plastic plugs. The idea is that
you can drill through a timber frame and into the underlying brickwork and
then insert the complete fixing in one go. I don't think they're suitable
for your job because as far as I know the longest available is about 6".

They're also a bit difficult to use because the screw part usually requires
a lot of force to drive in.
Only if you haven't drilled the correct size hole. 9.5 or 10mm IIRC.
