Abstract
Tongue and groove pliers include a first member having a slot, and a second member connected to the first member by a pin in the slot. The first member has a plurality of arcuate ribs defining open ended grooves on the side adjacent to the second member. The second member has a tongue on the side facing the first member. The tongue fits in a selected groove to adjust the spacing between opposing jaws on the respective first and second members. The pliers have at least one visual alignment feature to align the tongue with a desired groove. The alignment feature can be readily visible marks indicating locations of the tongue and/or grooves.
