    Exactly what I need

    Posted by James B on Apr 2nd 2022

    This is a long extension with a solid locking mechanism to firmly hold a socket. This works with my Stahlwille sockets and also my sockets by Hazet, Wera, and Wright. The fit on each branid of sockets is very good, and it does not fall off unless the button is pressed. The extension is straight, and the satin finish is without flaws. I recommend this extension to anybody looking for one.

    Stahlwille 1/2” Qr Extension

    Posted by David A Long II on Apr 21st 2019

    Loved the 1/4” so I knew I would love the 3/8” and 1/2” versions. The 1/4” used a locking hole in the female end but the 3/8” and 1/2” extensions are notched in the female end
