Score: 88/100Rankings

The Channellock GL6 is a compact 6.5-inch tongue and groove plier designed for gripping irregular shapes in tight spaces. Its main limitation is the restricted jaw capacity, making it unsuitable for large fittings. It is best suited for DIYers and mechanics needing a durable, USA-made tool for confined areas.

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.
