This is a lot of 3 vintage Petersen Vise-Grip pliers.
~ Two pairs of 7R pliers. There is a trigger on the bottom part of the handle that releases the jaws, as well as a knob at the base that adjusts the jaw spacing. They measure approximately 0.75" tall, 2.25" wide, and 7" long.
~ A larger pair of 10R pliers of the same design. This pair measures approximately 0.75" tall, 2.5" wide, and 9" long.
The lot comes in good pre-owned condition. The 7R pliers have some rust, while the 10R pliers are very rusty.
