Channellock GL6 2 in Blue
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 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.
