Probably left this a little late for a weekend job but since building my new desk I realised that all of my plug extensions are a little old and past it. I have the steel (like this) underneath the worktop to stop it sagging, so I'd like to tidy up my cables and find some nice surge-protected plug extensions that I can cable-tie to the steel underneath. Anyone know of any off-hand before I go off trawling the interwebz? I'm sure I've seen some before that have a little mounting "bracket" for cable-tying.
