I've bought a few lengths of grey pipe- lagging foam tube, then cut various lengths slightly oversize, to jam vertically and/or horizontally to hold items in place
Very handy...and cheap.
Apparently, they can also be used to lag pipes!
That's a great idea.
We have a few of these light spring loaded curtain poles that do the same job. Handy for keeping crockery & tinned goods where they belong..
As for the OP's original question, do you have a pic of your TV and bracket? It'd be interesting to know what your working with.
