As a vario pivot bench fixture system, the innovative design of this 2 piece optional add-on set allows maximized usage of both K-Body and even standard pipe clamps. The Maxis can be used with any length K-Body, bar or even pipe clamp, giving a nearly unlimited holding capacity. These are positive locking devices that can be fixed at any angle from 0° to 270°, allowing the user to perform awkward operations with ease by holding the work at a convenient angle. With the Maxis, you can turn a K-Body clamp into a European tail vise for edge joining and surface planing operations. Only available in pairs of 2 clamps.
