Product Description
DoubleGroove™ Tall Dogs
Innovative 20mm bench dogs ideal for securing guide rails or jigs to your perforated worktop
Special Note:
We've recently introduced a new product for use with Dog Rail Clips: Stubby Dogs. While our Tall Dogs, shown on this page, afford a maximum level of adjustability in the thickness of material you can cut, there is one trade off: Tall Dogs can obstruct movement of the Festool TS55 and TS75 along the guide rail. If you have a large enough 20mm table and don't tend to utilize the full length of your table when making cuts, you may never encounter this limitation. But for those using a standard Festool MFT/3 or smaller 20mm work surface, the low profile of the Stubby Dogs means you can cut along the full length of your guide rail. Bottom line: If you frequently cut materials one inch (25.4mm) or thinner, we recommend you choose Stubby Dogs. If you frequently cut materials thicker than one inch, stick with the Tall Dogs on this page.
About the DoubleGroove™ Dog Family
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.
DoubleGroove™ Tall Dogs measure 70mm above the collar, and 18mm below the collar. This makes them the perfect size for securing your guide rail, when used in combination with Dog Rail Clips. A unique design element—an easy-on taper at the top of each Tall Dog—simplifies the process of attaching your guide rail. (See the video below for a depiction of this process.) To accommodate clamping, an included M8x1.25 threaded hole at the bottom of each dog accepts our M8 SpeedKnobs™, 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 DoubleGroove™ Dog family includes a variety of sizes: Small (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), Tall (the product on this page, for using in conjunction with Dog Rail Clips to secure your guide rail to your worktop), and Stubby (also designed for use with Dog Rail Clips, but with a shorter height to clear your track saw motor housing when plunge cutting). Additionally, specialized "Close Fit" versions of our Small, Large, Tall, and Stubby Dogs are available for those who want a tighter fit in 20mm worktops made with precision tools (e.g. CNC router or the Parf Guide System).
- Easier to Use: Twin grooves running along the collar make DoubleGroove Dogs easier to remove than other dogs on the market; no more stuck dogs!
- Optimized for Guide Rails: DoubleGroove™ Tall Dogs feature an easy-on taper designed into the top, which simplifies the process of attaching your guide rail to the worktop.
- A Perfect Fit: Precision machined to exacting tolerances, with a diameter of 19.9mm to strike the perfect balance between solid, secure mounting and ease of insertion/removal.
- Ideal for Custom Worktops: If you've made your own perforated worktop based on the 20x96mm standard and aren't quite sure if your tolerances are perfect, you'll likely find DoubleGroove Dogs to be a better choice. Their twin collar grooves will make it easier to remove dogs that might become "too snug," and a swept undercut along the collar means DoubleGroove Dogs will mount flush even if your holes have tearout.
- Clampable: Each dog includes an M8x1.25 threaded hole, perfect for use with our SpeedKnobs to secure the dogs inside your 20mm perforated worktop. (If you already have the knobs from Festool's 488030 Clamping Elements, those will work too, but you'll find our SpeedKnobs to be much faster and easier to thread.)
- Material: 6000 series aluminum alloy, T5 tempered and anodized clear

Additional Photos & Applications
DoubleGroove Dogs™ can be used to secure your workpiece to your perforated worktop at perfect 90 or 45 degree angles. When used in conjunction with Dog Rail Clips, our dogs can also be used to secure your guide rail to your worktop.
DoubleGroove™ Dogs will be a snug fit in your perforated worktop, but if you need an extra degree of security, all of our dogs feature an M8x1.25 threaded hole accepting TSO SpeedKnobs™ (our preferred, super quality M8 knob), FESTOOL® clamping elements knobs, or off-the-shelf knobs with M8x1.25 threads.(DoubleGroove Tall Dog shown in the picture above.)

TSO tall bench dog
Be careful! This does not work well in a Parf system. way too much movement because it is long and tall. Buy the other dogs made for the Parf system, you will be much happier. I later bought the stubby close fit bench dog and was happier. The tall dogs hit my Makita track saw battery if I have wider material to cut. Make sure to buy Close fit bench dogs on a Parf system.
