I probaly didnt word my post correctly.

Im actually after the rubber 'grommet', the black circle thing with the wire going through it in the middle.

Im having a hard time finding on, mainly because I have no idea what they are called. Only place Ive really seen them is on towel holders...

Anyway thanks for the link, might have to try and find a shop that sells it
