This is the 10-inch straight-jaw tongue-and-groove plier that gave Channellock its name. The jaws are forged from high-carbon U.S. steel and the 90-degree teeth are precision-machined and laser-hardened, so they grip pipe and fasteners without rounding the corners off after a season of use. The PermaLock fastener replaces the nut-and-bolt joint that loosens on cheaper pliers, keeping the two halves in alignment.
The 430 is the size most people reach for first — big enough for plumbing fittings and pump nuts, still slim enough to work inside a cabinet or under a sink. The tongue-and-groove channels reset jaw width one-handed while keeping the handle span comfortable, and the grips stay put with wet hands.
Channellock has been forging pliers in Meadville, Pennsylvania since 1886 and remains owned by the DeArment family. Its snips, non-locking pliers, drivers, pry bars, and ratcheting wrenches are 100% Made in the USA. The 430 carries the Built Strong limited lifetime warranty, which covers defects but excludes worn or abused cutting edges, loose joints, and alterations.
