  • Smart Connect Dogs are the easiest way to connect/layer 20x96mm work surfaces. Just slide these dogs into chamfered holes and secure via a clamping knob underneath.
  • We recommend using Smart Connect Dogs with M8x1.25 clamping knobs such as our M8 SpeedKnobs or M8 Star Grip Knobs shown in this picture.

We're excited to partner with Ron Paulk to offer a bench dog like no other: the Smart Connect Dog. Unlike traditional bench dogs which protrude from the work surface to act as a material stop, Smart Connect Dogs feature a chamfered lip that seats flush or slightly underneath your work surface. If you've been following Ron's latest bench and router table designs, you'll see him relying on layered panels to create flexible, expandable, portable work surfaces—and we love the idea. When it comes to layering or connecting work surfaces, rather than relying on clamps (expensive, imprecise, subject to getting knocked out of alignment) or traditional 20mm bench dogs with collars (which take up worktop space), Smart Connect Dogs used with our economical M8 Star Grip Knobs or more premium M8 SpeedKnobs provide strong clamping action, precise registration and won't interfere with your work. With a body length of 28mm, Smart Connect Dogs are perfect for layering/connecting two 15mm (or 5/8") thick plywood panels with knobs clamping from underneath, as Ron demonstrates in the video to the right. This is just one creative use for Smart Connect Dogs; we know the TSO user community will come up with even more great ideas! (And please share them with us.)

To flush mount Smart Connect Dogs, you will need to chamfer the 20mm holes on your work surface. We recommend using a trim router with a quality 45˚ chamfer bit, as this allows you to perfectly adjust the depth of the chamfer to match these bench dogs. We do not recommend using the fixed-cut-depth of the UJK Chamfer Tool which is not suitable for plywood.

    Great product! Sturdy, machined well, and perfect for sandwiching two layers of plywood or affixing jigs to an MFT. A good bet I'll be buying more down the road.

    Bench Dogs to fit flush with an MFT table surface

    Posted by King Waters on 27th Jul 2022

    This dogs offer a threaded flush-fit for your MFT table. They fit within the beveled edge of a 20mm dog-hole, allowing nearby operations to be free of interference. Like all of TSO's products, quality is the highest priority. I have read some internet comments that the fit of these may allow some movement. Once they are secured by a TSO speed knob, with the bevel well-seated, you will probably find such comments a bit picky.

    Well worth the wait. These dogs are great for jigs and other fixtures. Also great for putting a temporary mft style top on sawhorses. I’ll be ordering more.

    Can’t wait to get more smart connect dogs

    Posted by John on 20th Mar 2022

    Love these dogs! I’m a fan of the 20mm dog hole work surfaces, and work in a small shop. These dogs help maximize flexibility within my limited space. Looking forward to ordering more as soon as they’re available.
