DoubleGroove Dogs are just part of a complete line of innovative workholding solutions from TSO Products. We've reinvented the modern 20mm bench dog and, in the process, addressed some common frustrations. Having dealt with our fair share of ill-fitting or "stuck" dogs, we've designed our dogs with twin grooves that run along the collar. While it may not seem like much, these double grooves make it much easier to remove the dog once it has been installed. Sharing the same careful attention to detail that has set our precision tools apart, small but important design elements—like the tiny undercut beneath the collar that guarantees a perfect 90 degree transition, even if the holes in your work surface aren't perfectly devoid of tearout, or slight chamfers along the touchable surfaces—result in a tool that's comfortable, accurate and a pleasure to use.
DoubleGrooveTM Small Dogs measure 18mm from collar to bottom, making them the perfect size for most perforated worktops including the Festool® MFT/3. To accommodate clamping, an included M8x1.25 threaded hole at the bottom of each dog accepts our M8 TM, FESTOOL® M8 knobs from the clamping elements kit, or any other similar off-the-shelf M8x1.25 threaded knob. All DoubleGroove Dogs are made in the USA from 6061-T6 aluminum on high-precision CNC machining centers and clear anodized for maximum durability. Sold in pairs.
The DoubleGrooveTM Dog family includes four sizes: small (the product on this page, ideal for most general use applications), medium (for use with our PTR-18 Precision Triangle or thicker work surfaces), large (for use with our MTR-18 Precision System Triangle), and tall (for using in conjunction with Dog Rail Clips to secure your guide rail to your worktop).
