A Versatile Addition to Your 20mm Hole Patterned Worktop
Watch this video for a glimpse into some of the many use cases for this versatile accessory and perfect companion to your 20mm workbench.
If we could pick only one accessory for our 20mm hole patterned worktop, it just might be a pair of these TDS-13 Dog Stops™ purely for their versatility. Distinguished by their low profile of just 9.5mm (⅜”) in thickness and extended length of 340mm (13-⅜”), a pair of our TDS-13s are a great solution for:
- Workpiece locating and general workholding. Need to cut a series of identically sized cabinet components? Measure just once, install a pair of TDS-13 Dog Stops and extend them so they contact your workpiece opposite the edge to be cut, and lock them in this exact position by securing two hex screws from the top. The TDS-13 retains its position—even when removed or re-installed into your worktop.
- The ultimate material stop. Domino® mortising, sanding, planing and scraping are all made easier with the TDS-13 used as an extended length material stop. Deploy a pair of TDS-13s in perpendicular positions to capture your workpiece along two edges, or use in conjunction with an inline clamp like our Power-Loc Toggle Clamp to completely immobilize it. At only 9.5mm (⅜”) thick, you can comfortably sand, plane and scrape workpieces as thin as ½” (12.7mm) without worrying about the TDS-13 interfering with your work.
- A 45° or 90° fence for precise cuts with your track saw. With its extended length, the TDS-13 can span four 20x96mm dog holes when positioned at 0 or 90°, or three dog holes when positioned at a 45° angle. It’s thin enough to fit under a guide rail, making it an ideal material stop for track sawing operations. Butt the ends of two TDS-13s together and you now have a contiguous fence measuring 680mm (26-¾”) in length.
- Verify squareness. Position two TDS-13s in a perpendicular layout to quickly validate the squareness of a drawer box, or force it square during glue-up with an inline clamp.
Even when removed and re-inserted, the TDS-13 returns exactly to its original position thanks to the inclusion of two DoubleGroove Chamfer Dogs. Unlike traditional bench dogs which typically feature a large diameter collar that extends above the worktop, these dogs feature a small 45° chamfer allowing them to sit flush with your work surface. This design detail also allows us to make the TDS-13 as thin as possible.
Don't Forget to Chamfer!
To get the best experience with our TDS-13 Dog Stops, you must use them in chamfered 20mm dog holes. We offer a Hand Chamfer Tool suitable for adding this chamfer to MDF/HDF worktops, as well as a Combined Chamfer & Reamer Tool which adds the chamfer while also enlarging your dog holes with uniform precision. For hardwood veneered plywood, a quality 45° chamfer router bit will make quick work of chamfering your dog holes. Chamfering your work surface holes provides another added benefit: by removing the hard edges, you reduce the likelihood of pinching a finger. (Not that it's ever happened to us.)

- Hand Chamfer Tool – For hand-cutting the perfect chamfer in your MDF/HDF worktop or Festool MFT/3.

TDS13
A great help for stabilizing and aligning my work on the dog hole table.

Adjustability/Must have
These dog stops are a must have. They complete my MFT/3 and are the most versatile while being easy to adjust. The flexibility in adjustment makes them perfect for versatile angles and parallel/perpindicular reference points for work pieces. The unquestioned accuracy for the alignment of 45/90 degrees in the MFT/3 is incredible. The low profile is where the magic is since they are perfect references while not getting in the way.

TDS-13 Low Profile - Outstanding
Perfect adjustable low profile product. This is just what I needed in so many woodworking projects. I've always managed to get the job done but easier is better!!

Very good quality
I only assembled them and worked with them for 15 minutes. I’m sure they will meet my expectations without any issues.
