CNC machined from 303 stainless steel, UJK Technology Parf Super Dogs precisely match the holes made by the UJK Technology 20 mm cutter. They are compatible with the Festool MFT/3 tabletop and other grid tables with 20 mm holes. In order to overcome the tolerances in the dog hole the Parf dogs clamp to your table using a threaded knob at the top. Once locked, there is no wobble or movement. A simple twist of the top in the opposite direction releases the dog. The Parf Super Dog comes with three interchangeable collars (flush fit colllar, Ø 25 mm original parf dog geometry and a chamfered stop collar). The stop collar provides a register ensuring the dog sits exactly at 90° to the work surface when locked in place. You can also insert the Parf Super Dog from beneath the table and lock it for use as a low profile dog. Supplied with two spare O rings.
