Right, missed the bit where it is bigger than the recess.

My suggestion is out then.

How about brass sash window fasteners? They would luck smart and unobtrusive on the wall. Scred down tight so zero movement.

They would have worked `pache.

Albert / snakey - I`ll take a pic when I get chance - but imagine an alcove in a wall, with a TV in; and a wooden sill board.

We`ve routed a slot in the wood, to take a tongue on the bottom of the board...about 10mm deep

BUT I needed to hold the top solid - whilst leaving an aesthetic look when the board wasn`t there...............

So I used:

2 off, 1/3  and 2/3 across the top........slot the board down, push back, and drop bolts Job done.

When removed, there are just 2 brass bolts on the wall.....

ah, get it now, almost like a window space, except with a tv and not a window.
