The Channellock 428 is an 8-inch straight-jaw tongue and groove plier with a 1.5-inch jaw capacity, the patented SAFE-T-STOP finger-pinch-prevention feature, and Channellock’s Permalock fastener. Jaws are laser-hardened 90-degree right-angle teeth that grip in both directions; the handles are dipped blue for comfort.
The straight-jaw profile grips both flat and round surfaces — the versatile pick over curved-jaw pliers when the tool has to work on both square fittings and round pipe. SAFE-T-STOP matters on a real job: tongue and groove pliers close hard and fast when a fitting gives way, and the stop physically blocks the jaws from shutting on the thumb. Permalock replaces the nut-and-bolt fastener found on bargain pliers — nothing to loosen, nothing to back out, no joint slop over time. Right-angle teeth laser-hardened into the jaw bite deep without stripping; the rust-prevention coating on the forged high-carbon U.S. steel extends tool life in truck boxes and humid jobsite conditions.
A daily-carry tongue and groove for plumbers, service techs, and homeowners who work on both threaded fittings and rounded pipe — 8 inches is the pocket-carry size most techs prefer.
Channellock has forged tongue and groove pliers in Meadville, Pennsylvania since 1886. The 428 is declared Made in USA on the Amazon listing.
