These bell push buttons can be used with any make of wired doorbell. They can alo be made to work with wireless systems if connected to a Wired to Wirefree Extender - Click here for extenders. The term, Flush Fitting, means that the movement of the bell push button is behind the front plate, so there is always a need to have a hole made behind the plate to accommodate this movement. However, for most of the round bell pushes there are options for oak or mahogany plinths - Click here, or we supply bell pushes and plinth combinations - Click here. When mounted on a plinth, there is no need for a large hole behind, just a hole for wires.
