Channellock Tongue and Groove Plier 420-1.5-Inch Jaw Capacity, Straight Jaw - 9.5-Inch

The Channellock 420 Tongue and Groove Plier is a 9.5-inch hand tool designed to grip, turn, and hold various workpieces. Built for users who need dependable mechanical leverage, it provides an adjustable grip for plumbing fittings, pipe, and everyday fasteners.

This tool features an undercut tongue and groove channel design engineered to keep the tool securely engaged without slipping under load. Channellock incorporates its Permalock fastener system, which eliminates traditional nut and bolt failure at the pivot point to maintain reliable alignment over continuous use.

Because this model uses a straight jaw configuration with a 1.5-inch maximum capacity, it will not suit larger pipes or fittings beyond that measurement. In addition, those who prefer curved jaws for round stock may find the straight profile less specialized for specific pipe work.

Verdict: The Channellock 420 is an excellent choice for anyone needing a dependable, American-made adjustable plier for standard household and mechanical tasks. It delivers solid jaw stability and slip-free performance for items up to 1.5 inches.
