TEKTON impact drive accessories complement your existing socket system. This set includes 1/2 in. drive 3, 6, and 10 in. impact extensions, along with an impact universal joint, adapter, and reducer. Attach an extension to your drive tool for reaching past obstructions or into tight, narrow spaces with your socket. Reach around obstructions and access fasteners at an angle with the universal joint. The adapter allows you to adapt 1/2 in. drive tools to 3/4 in. drive sockets, and the reducer adapts 1/2 in. drive tools to 3/8 in. sockets. The included organization rail comes with twist lock clips and top-mount extension holders. Ridges along the rail prevent the clips and holders from sliding, and a keyhole slot helps it lock into a tray.
