Score: 82/100Rankings
The Channellock GL12 is a 12.5-inch GRIPLOCK Tongue and Groove Plier designed for electricians and plumbers to grip irregular shapes and 1/2-inch electrical fittings. It features a laser-hardened jaw, PERMALOCK fastener, and an ergonomic offset head for enhanced leverage and durability. It is ideal for tightening conduit locknuts, gripping round tubing, and maintenance on fittings where standard pliers slip.
The Channellock 440 is a 12-inch straight jaw tongue-and-groove plier built for heavy-duty gripping tasks with a PERMALOCK fastener. Its significant weight can cause fatigue during prolonged use, and it lacks the quick-adjust features of newer models. It is best suited for professional plumbers and mechanics needing reliable, high-capacity gripping.
