Dyna-King standard jaws are made from hardened steel and can hold from an 8/0 hook size to size 22. The midge jaw (order separately) will hold from size 10/0 to 28. Vises rotate a full 360º for full tying access, with hooks secured tightly by forward closing jaws that have an easy turn “notch lock” cam that stays dead tight until released. All Dyna-King vises fit both pedestal and clamp bases. The pedestals are correctly weight-proportioned to the dimensions of their corresponding vises, and have non-skid feet. Dyna-King guarantees the vises to be shipped in perfect condition, and they come with a lifetime warranty. The jaws have a two-year warranty.
