I'm sure I've come across a surface-mounted channel system into which mains sockets can be inserted at any point, with blanking plates filling in the intermediate spaces; the wiring was built in to the strip itself. But I've searched in places like Screwfix and TLC (and office suppliers - I think it was an office rather than an industrial product) without success.
I tried Googling for "power strip" but that seems to be the new name for what I would call a multi-socket extension - when did that happen? The product I'm thinking of comes in much longer lengths, to be run across the entire width of a room.
Can anyone point me in the right direction? Many thanks.
