The round bench dogs are made from solid brass rod and can be installed in any bench by drilling a 19mm (3/4in) hole. Brass dogs are non-corroding and kind to your tools. The combined crosshatching and 2° inward slope of the face hold wood securely. The side spring lets the dog slide smoothly, but holds it well at any desired projection.
The bench dogs (at 110mm) are standard length. The Bench Pups® (at 60mm) are fine for benches with tops up to 51mm thick and ideal for bench sides; just drill holes in the skirt or the edge of the top.
Both work well with the Wonder Clamps.
