UJK 20mm Bench Dog Hole Plugs are supplied in sets of 40 pieces, made from durable polymer, designed to close 20mm holes in multifunction tables when not in use. They prevent small objects and tools from falling through the holes, protect saw blades from accidental cuts on the tabletop, and keep the work surface flat. Removal is tool-free thanks to the integrated grip system. Compatible with the Festool MFT/3 table and all grid tables with chamfered 20mm holes, self-built using the Parf MkII drilling system. Made in Great Britain. Distributed in Italy by Krollit, official UJK distributor since 2007.

| Profile |
Compatibility |
Reason |
| Woodworker with Festool MFT/3 table or Parf MkII grid table |
Suitable |
40 plugs cover half of the MFT/3 table holes; with 2 sets, the entire surface is covered, keeping the work surface free of openings when bench dogs are not inserted |
| Anyone using a track saw on a multifunction table |
Suitable |
The polymer of the plugs protects the saw blade from accidental cuts on open holes during work across the entire table surface |
| Anyone working with screws, dowels, and small accessories on the table |
Suitable |
The plugs prevent small objects and tools from falling through the 20mm holes, a common problem during work on multifunction tables with an open grid |
| Anyone with tables with 20mm holes without chamfer |
Not suitable |
The plugs require the standard chamfer around the hole for correct insertion; for tables without chamfer, a UJK chamfering tool is needed before use |
Not suitable for: tables with 20mm holes without chamfer and for holes with a diameter other than 20mm.

Frequently Asked Questions
How many plugs are needed to cover the entire Festool MFT/3 table?
The Festool MFT/3 table has 77 total 20mm holes. One set of 40 plugs covers approximately half of the table. To cover the entire surface, 2 sets of 40 plugs are needed, for a total of 80 plugs (3 spares compared to the 77 holes).
Those who only use a portion of the table continuously can cover the holes in the most used area with a single set, moving the plugs to the necessary positions during work.
How are the plugs removed without tools?
Each plug has an integrated grip system that allows for tool-free removal with your fingers. The system is designed to allow quick removal during work without interrupting the workflow.
Do the plugs really protect the track saw blade?
Yes. The polymer material of the plugs is soft enough not to damage the track saw blade in case of accidental contact during cutting. Open 20mm holes on the multifunction table, if not covered, would expose the blade edge to contact with the metal edge of the hole.
The use of plugs is particularly recommended during operations involving cuts across the entire surface of the table, where the track saw may pass over holes not covered by bench dogs.
Are the plugs compatible with self-built tables using the Parf MkII drilling system?
Yes. The plugs are compatible with all grid tables with chamfered 20mm holes, including self-built tables using the Parf MkII drilling system. The requirement is the standard chamfer around the hole, which ensures correct insertion and secure fit of the plug.
For self-built tables without chamfer, the UJK combined chamfering and reaming tool is available, which allows adding the chamfer to existing holes before installing the plugs.
Are the plugs used during work or only when the table is not in use?
The plugs can be used in both situations. During work, they are inserted into holes not occupied by bench dogs to protect the saw blade and prevent accessories from falling. When the table is not in use, they cover all holes, keeping the surface flat and reducing the accumulation of dust and chips inside the holes.
