Channellock gls-1 Tongue and Groove Plier Set 10 12 Inch

Product Description

The CHANNELLOCK gls-1 is a two-piece tongue and groove plier set designed for professional trade use in plumbing, HVAC, and general mechanical service. The set includes one 10-inch and one 12-inch plier, both featuring a hex jaw profile that grips hex fasteners, pipe, fittings, and irregular shapes without slipping. An ergonomically designed offset head increases leverage at the point of work, reducing hand fatigue during extended use. The PermaLock fastener replaces the traditional nut-and-bolt pivot, eliminating the failure points associated with conventional adjustment hardware. These pliers are built for technicians who need reliable grip across multiple fastener and pipe geometries.

Tongue and groove pliers are a daily-use tool across plumbing, HVAC, and electrical trades. The 10-inch length suits tighter access points and smaller fittings, while the 12-inch handles larger pipe, conduit fittings, and hex-head fasteners. The hex jaw geometry makes the set especially useful when working with hex nuts, union fittings, and supply valves where a standard slip-joint jaw would round the workpiece. The set is appropriate for both residential and light commercial service work.

Installation Notes

Tongue and groove pliers are a hand tool requiring no installation. Before servicing any system, follow lockout/tagout procedures and shut off all relevant utilities including water supply, gas, or electrical power as applicable. Select the jaw position that provides full contact with the workpiece to avoid rounding fasteners or fittings. Inspect the PermaLock pivot and jaw condition before each use and remove from service if wear or damage is observed.
