Anyway back on topic the T+K bracketts are just the shape T at the top and
K shape at the bottom. One thing I forgot to add was the wall type it's a
'breeze block' construction or cemet block I think that's a cinder block in
the US, and the wall has a filled cavity.


I used 10mm resin anchors for a similar installation into brick, they have
the advantage of being less likely to crack the brick as compared to
expanding/rawl bolts. Breeze block is a dubious material, depending on it's
strength it may or may not be ok. If it is a dense concrete block you should
be ok, but I'd recommend resin type anchors anyway. I got mine from screwfix.
