Finding that elusive 10mm socket in an unorganised tool box is nearly impossible. Thank to Kincrome, keeping your sockets safe, secure and organised has never been easier with the Kincrome Socket Rail Kit. The clips feature a ball bearing style latching system, similar to that found on a quick release ratchet, keeping your sockets store securely. The clips are easily removable and interchangeable between rails, allowing you setup your sockets how you please. This kit includes 20 x 1/4", 17 x 3/8" and 14 x 1/2" drive socket clips.
