Palmgren Dual Force Precision Mechanical Booster Machine Vises

• Adjustable clamping pressure provides consistent, continuous force of up to 11,200 pounds (50KN) maximum making part holding simple and easy.
• Precise clamping force regulation (patented) is achieved by turning the force ring to one of three graduation settings and a simple turn on the handle provides precise clamping pressure every time.
• Mechanical booster (patented) delivers a steady clamping force and is equipped with an internal disc spring design that guards against shocks and vibrations maintaining consistent pressure during the machining operation.
• Incorporates the Dual-Force design of all directional alignment with a 12 pound of downward force for every pound of horizontal force.
