Ok see that many people seem to have a whole lot of connections for different tools, brushes etc.
But the fact is that all manufactures try to make there own connections, that are unique to there handles or any other tools they
have including angle adapter connections.
Only have to check some of the pole connections and have some sort of different way of connecting there brushes.
Also take note most are not interlocking with any other tools if you may want to use on a pole.
But instead have the squeegees / scrubbers connections on a different connection.
This is when I developed the quick-lock.
The intention was to have an universal angle adapter pole connection, that could be used on all tools without the need to change your pole or connection.
Myself done this with all our tools.
Have shown numerous videos on how to do this.
And know most people are not inclined to do this which I understand.
(But if you are, try it.)
And if you happy with what have now, that's OK as well.
Maybe a manufacture may come out ready quick-lock connection systems like described.
Universal connections one day.
Here is the original video of the quick -lock.
