I use Moerman, think they are fantastic. I found that the standard lightweight alloy mop handles with the screw thread fit perfectly. Use them on the few shop windows/showrooms that I do.

You can do this easy modification on just about any handle.
The big secondary benefits with this on end of handle are.
Extended length for people having problems holding/griping.
because handle is ether to short, thin or both.
Square lock also allows you to grip in a more natural way having better control of the squeegee.
Because of this you have less likelihood of cramping and or developing RSI hands, wrists etc.
