Stahlwille 11021000 407QR QuickRelease universal joint, 1/4″ Drive

The QuickRelease system secures every single link in the tool chain, from the ratchet to the extension to the socket. Unlike other locking systems that only fix the first insert tool on the ratchet, this mechanism is easily accessible and ergonomically optimized, securing the tool without taking up extra space. It provides more efficiency by making tool changing both safe and quicker.
