This genuine Channellock Model 460, 16.5-inch, straight-jaw, tongue-and-groove plier is made in the USA. The Model 460 plier has an overall length of 16.5 inches (419.9 mm), and the undercut tongue-and-groove design won't slip, allowing you to securely adjust the jaws to 8 different positions up to 4.25 inches wide (108 mm). Within the jaws are extremely durable, right-angle, laser-heat-treated teeth that provide a powerful grip. This Channellock plier is made of high-carbon steel, specially coated for rust prevention, and assembled with a PermaLock fastener that eliminates nut and bolt failure common to lower-quality pliers. The possibility of stress breakage is minimized by Channellock's patented reinforcing edge, and the trademark Channellock Blue grips make this tool more comfortable to use. Channellock, Inc. manufactures a wide array of high-quality, general-purpose hand tools as well as specialty tools for electrical, plumbing, automotive, agricultural, and HVAC projects.
