Channellock 440
Score: 82/100Rankings

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.

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.
