The TEKTON 37526 is a 16-inch groove joint (tongue-and-groove) pliers with a 4-1/4 inch jaw capacity — built for the plumbing and pipe-fitting work that smaller pliers can’t handle. The multiple jaw positions keep the handles parallel at every opening size, so you get full hand leverage whether you’re gripping a 1-inch pipe or a full-size fitting.
It’s sized for plumbers, tradesmen, and anyone working on industrial-scale pipe, conduit, and large fasteners where handle length is what turns squeezing effort into real gripping force. Serrated jaws bite round stock without rolling off, the pivot holds its adjustment positions under working load, and the long handles give you the torque to crack stuck fittings loose without resorting to a pipe wrench.
TEKTON is a Grand Rapids, Michigan tool company that builds a dedicated Made-in-USA line alongside its global catalog. The USA-made tools — screwdrivers, picks and hooks, punches, chisels, and pry bars — are manufactured in the United States and clearly marked as such, so you know exactly what you’re buying.
