At 4-1/2 in length, the 424 is the smallest straight jaw in the CHANNELLOCK® tongue-and-groove family and can be easily and conveniently transported in a pocket or small tool bag. This plier is built to last with a PermaLock® fastener to eliminate nut and bolt failure, patented reinforcing edge to minimize stress breakage and right-angle, laser heat-treated teeth to provide a better, longer lasting grip.
