1/4 Drive Rola Ratchet. This clutch driven ratchet used to install and remove Hi-Lok? & Hi-Lite® fasteners is designed for smooth, positive engagement in limited access areas. The design permits maximum rotation with minimal handle rotation, resulting in no lost motion as with other ratcheting assemblies. Easily reversible by removing retaining clip and pushing the head through then inserting in the opposite side. A hole through the head permits use of an Allen wrench to hold pins tight. Also comes with 3 Hi -Lok sockets. This set is in excellent condition never used. Just has my initials engraved on items.
