Score: 80/100Rankings

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 426 is a 6.5-inch straight jaw tongue-and-groove plier designed for versatile gripping in tight spaces, manufactured entirely in the USA from high-carbon steel. It features a PERMALOCK fastener and laser-hardened teeth to prevent slipping, making it reliable for general maintenance. However, its compact size restricts leverage and limits its use to objects up to 0.87 inches.
