The CHANNELLOCK INC GS-1 is a 2-piece pliers set designed for trade professionals who need versatile gripping and adjustment capability on the job. The set includes two tongue-and-groove pliers: a 9.5-inch model with 5 adjustments suited for larger fasteners, fittings, and pipe work, and a 6.5-inch pocket-size model also offering 5 adjustments for tighter spaces and lighter-duty tasks. Both tools feature plastic grips and are packaged together in a clamshell package. Plumbers, HVAC technicians, and general trades keep sets like this on hand for quick access to two common grip sizes without carrying a full tool roll.
This set covers a wide range of residential and light commercial service tasks. The 9.5-inch pliers handle larger pipe fittings, conduit connectors, and nuts, while the 6.5-inch model is compact enough for confined spaces such as panel knockouts, valve stems, and under-sink work. The clamshell packaging makes the set a practical stocking item for supply houses and tool kits alike. It is well-suited for plumbers, pipefitters, HVAC service technicians, and electricians who routinely need adjustable grip pliers in two sizes.
Designed as a general-purpose 2-piece pliers set for use across plumbing, HVAC, electrical, and general mechanical service applications. The set includes components referenced as Model 420 and Model 426.
These pliers are hand tools requiring no installation; however, always match the correct plier jaw size to the fitting or fastener being worked to avoid rounding edges. When working on live plumbing or gas systems, shut off supply valves and depressurize lines before using any hand tools on fittings. Electricians should confirm circuits are de-energized per NFPA 70 before using pliers near energized components.
