ABSTRACT:
A clamp (16) has movable and fixed ledges (58, 82) extending forwardly towards one another from posts (38, 40) on the clamp's halves (34, 36). The movable ledge receives a door whose weight moves the ledge in a generally gravitaionally downward direction to move post (38) towards post (40) and to clamp the work piece therebetween. The fixed ledge is positioned in the path of movement of the door and the movable ledge to limit the movement and any excessive pressure which otherwise might be exerted on the door by the clamp halves. The clamp is mounted on a base (14) which comprises angled piping (20, 22) to form a two-dimensional support for the clamp and the door. Insulated electrical wires (22) extend through the piping. Sockets (26) are secured at one or more ends (24) of the piping, save for one, to provide electrical outlet connections for power tools. The insulated wire extends from the remaining piping end (32) for connection to a conventional electrical outlet.
