The Channellock 426 is the original straight-jaw design that made the company — a 6.5-inch tongue-and-groove plier with flat parallel jaws that grip square nuts, bolts, and fittings cleanly without the round-stock rocking you get from V-jaws. Laser-hardened 90-degree teeth and the PermaLock fastener keep the tool tight for years, and the protective coating keeps rust off in tool rolls and wet conditions.
It’s sized for plumbers, HVAC techs, and maintenance workers who need a pocket-friendly plier for fittings, supply lines, and small fasteners. The undercut tongue-and-groove locks through its adjustment positions and resists slipping when torque is applied at an angle — the usual failure mode on cheaper adjustable pliers.
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.
