Single-wedge model

Pull-down workholding clamps generate pull-down action, pressing workpieces down onto the fixture base, as an alternative to applying sideways force to the jaw on the fixture base.

The OK Vise single-wedge pull-down clamp design is a standard single-wedge clamp (inverted ) and combined with a pull-down set (a combination of a plate and a bushing).

The major differences of single-wedge pull-down clamp when compared with double wedge pull-down clamps are :

• There are more variations of jaw types and clamp sizes.
• The angle of the movement is steeper.
• It is easy to test fixture with and without pull-down property.
