Does anyone remember those toilet closer thingo's that we use to have.
A sort of long bit of thick wire connected to the frame and door - that made the door close when it was opened. Sort of put pressure on it - and it forced the door closed after you came in or went out. BUT - not with any real force - just enough to close the door.
I'm having problems finding them.
OR - are they something builders just use to do - ie cheap and easy.
