Abstract: A clamp used in the manufacture of cabinets to aid in the blind fastening of finished drawer fronts to drawer boxes. The clamp is comprised of an inverted U shaped channel(6) of a predetermined length. The top section(6b) of the channel is sufficiently thin to fit in the desired spaces between drawer fronts or other finished cabinet members commonly referred to as “reveals”. Further, the top section is substantially flat on the exterior surface. The channel is of sufficient width from side to side to contain the finished drawer front (17), the front of the drawer box (16) and the rigid plate (13) and necessary play. A shaft (7) is passes through side (6a) of the channel and a rigid plate (13) is attached by pivotable means to the end of the shaft projecting into the channel. The shaft and plate are advanced toward the opposite side (6c) of the channel by threaded, friction or cam action means.
