This is essentially a low-profile bench dog with a quick-release sliding jaw for holding work. Dubbed a "blade" due to its flat design, it projects just 6.4mm (1/4in) above a work surface to permit maximum access to a work piece. Used much like a toggle clamp, it has a thumb-operated eccentric cam lever to control the sliding jaw, so you can quickly secure or release work.
With 6.4mm (1/4in) range of travel, the jaw has limited throw, but applies up to 135kg of clamping force. Flats on the cam provide secure stops at 3.2mm (1/8in) and 6.4mm (1/4in) of travel. The 38 x 6.4mm jaw face has a 5° inward cant to help hold wood securely. The cam and jaw are cast steel, heat-treated for surface hardness, and the post and wedge-lock mechanism are turned steel.
The standard post version is for use in a through-hole or a blind hole that is at least 47.5mm deep.
