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 1/4" above a work surface to permit maximum access to a workpiece. 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 1/4" range of travel, the jaw has limited throw, but applies up to 300 lb of clamping force. Flats on the cam provide secure stops at 1/8" and 1/4" of travel. The 1 1/2" × 1/4" 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 1 7/8" deep. The wedge-lock version is usable at any angle from horizontal to vertical and anchors firmly in a through-hole in material as thin as 5/8" (depending on the strength of the material) or in a blind hole that is a minimum of 1 3/8" deep. Both styles of post are available sized for 3/4" or 20mm diameter dog holes.
The T-slot track version replaces the post with a 1/4-20 T-bolt. It can be secured at any point on the track using a hex key, which also locks the orientation of the jaw.
