It all started with our invention of the Rue Ring Locking Cotter Pin. We went on to develop Nylon LanyardsTM, Bow-Tie Locking CotterTM Pins, Infinity S-HooksTM, our hugely popular SLIC PinsTM, our Auto-Lock Safety Pull Pins, and our newest invention: the Unitary Plunger SLIC Pin (U.S. Patent No. 11,542,977). We are continually researching and developing new fastener solutions to solve fastening challenges. We're proud to offer these exclusive, award-winning product innovations.
