The IRWIN 2078110 is a 10-inch groove lock plier designed for gripping, turning, and holding pipe, fittings, and fasteners in demanding trade applications. Built with a patented Press-n-Slide button mechanism, the jaw adjusts rapidly along a double-capacity groove track, allowing the tech to set the correct jaw opening without repositioning the tool by hand. These pliers are a go-to for plumbers, HVAC techs, and pipefitters who need a reliable channellock-style tool that sets fast and holds firm under load. At 5.75 pounds per unit, the 2078110 is a solid, full-size plier built for daily professional use.
The IRWIN 2078110 is suited for residential and light commercial service work where quick jaw adjustment and secure grip are required. Typical applications include tightening and loosening threaded pipe fittings, adjusting packing nuts on valves, gripping irregular or round workpieces, and general mechanical assembly. The Press-n-Slide adjustment system makes these particularly effective in tight spaces where the installer cannot easily manipulate a standard slip-joint plier with two hands. These pliers are a standard addition to the tool pouch of plumbers, HVAC installers, and general maintenance technicians.
Designed as a general-purpose groove lock plier suitable for plumbing, HVAC, pipefitting, and mechanical service applications where a 10-inch adjustable jaw plier is required.
Groove lock pliers are used by licensed plumbers, HVAC technicians, and pipefitters as a hand tool — no power source or code permit is required for the tool itself. Always shut off water supply or system pressure before using pliers on live plumbing or refrigerant line fittings. Avoid using pliers on soft brass or chrome finish fittings without a protective wrap, as jaw teeth will mar the surface. Keep jaw pivot and adjustment channel clean and lightly lubricated for consistent slide action.
