The UJK Clamp Set is an exceptionally useful accessory for multifunctional workbenches and planers with 20mm holes. It allows you to clamp the workpiece from the side, leaving the top surface free of any obstacles for convenient routing, cutting, sanding, or carving.

The set includes:

• 3 UJK PUP clamps – precisely made steel clamps (12mm) for workbenches with 20mm holes
• 1 "Duck" – a side clamp in the shape of a duck with irregular curves, made from solid phenolic laminate 12mm thick. The clamp also has 2 holes for screws to permanently secure it.
• 4 positioning blocks made of HDF board (2 wedges, 1 spacer block, and 1 stopper block)
  (The stopper block has 3 holes for clamps; two are spaced 96mm apart for lateral or longitudinal positioning, and the third is for positioning diagonally.)

Depending on the width or thickness of the workpiece, one or both wedges and possibly the spacer block may need to be used.
