SnapLok Quick Disconnect Adaptor for Power Grip Handle - DQ-ADPT-L
 
For use with the Snaplok Power Grip Handle as it ensures quicker connection and disconnection of the rods. This stainless steel adaptor has enlarged shoulders on the dual buttons on this quick release adaptor for added strength.
 
The adaptor works on the basis of pressure and the angle of the SnapLok rod, so when you are sweeping with the rod at an angle, the downward pressure keeps the rod on the drill adaptor. As soon as you straighten the rod in parallel to the drill adaptor, you can just pull on the drill and the drill adaptor comes out from the rod fitting/ferrule.
