If you work with impact wrenches, this Proto J7203L 3/8" Drive Impact Socket Extension is a must-have. It will allow you to attach sockets to the drive of your impact wrench. This SAE extension has a locking design that allows it to be used with other extensions for added length and reach. The socket retention system ensures positive contact between the tool and socket, so you can apply torque without fear of slippage or loss of connection. The extension has an overall length of 3 in., which means it will fit well into tight spaces where standard extensions cannot go. The square drive size is 3/8", making it compatible with most impact wrenches on the market today. If you are looking for an extension that will provide excellent performance, this Proto J7203L is the perfect choice for you.
