The Proto PRO7515 Impact Locking Extension Set includes three 1/2" drive extensions (3", 5", and 10") designed for one-hand adjustments in demanding workshop environments. Each extension features Proto's exclusive Grip-Lock system, providing a tool-free way to connect your ratchet to the extension securely.
High-visibility orange knurling on the handle makes these extensions easy to spot in a cluttered toolbox or busy shop floor. Built to handle impact applications, this 3-piece set is a reliable addition to any professional or industrial toolkit.
