The M12 FUEL™ INSIDER™ Extended Reach Box Ratchet is a new-to-world solution that reinvents the traditional ratchet. The low-profile head design allows sockets & adapters to be inserted directly into the tool. Our M12 FUEL™ INSIDER™ delivers UNRIVALED ACCESS and over ¾” shorter head profile size with the socket to reach deep into the engine bay and fit into the tightest spaces.
