What size are the threads on top of the faucet that your tap handles screw on to?
Because that is the same size of screw on the bottom of this tap handle.
I can screw all my tap handles on this screw sticking out of the handle I just bought... is that confusing?
Top which is where my erdinger screws into
Bottom of ferrule which goes to tap (which is also the same size as my new handles threads)
The actual handle screw
So whatever thread is on the top of the faucet I need on both ends of my ferrule.
I hope this helps.
