The Channellock 430 is a 10-inch straight-jaw tongue-and-groove plier — the size most tradespeople pick first when they want a single pair of Channellocks on the belt. Forged from high-carbon U.S. steel with a special coating for rust resistance, the jaws grip pipes, nuts, and bolts through 90-degree laser-hardened teeth that stay sharp across years of service.
It’s sized for plumbing, automotive work, and home repair where jobs range from 1/2-inch supply lines to 1-1/2-inch P-traps in the same afternoon. The PermaLock fastener replaces the nut-and-bolt pivot that loosens under load on cheaper pliers, and the ergonomic blue non-slip handles cushion the hand on long jobs without the sweat-slip that bare-steel grips develop.
Channellock has been forging pliers in Meadville, Pennsylvania since 1886 — the same small American factory, now five generations into the same family. The company is known for the blue-handled tongue-and-groove pliers that defined the category, and every tool in the core line is made in the USA from forged high-carbon American steel.
