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 424 is a compact, 4.5-inch straight jaw tongue-and-groove plier designed for precise gripping in tight spaces. It features a PermaLock fastener and laser-hardened teeth, making it ideal for small-scale mechanical and plumbing tasks. However, its limited jaw capacity makes it unsuitable for larger objects or heavy-duty work.
