ABSTRACT:
A framing form and clamp includes a support or base having a plurality of guideways for mounting framing blocks. A belt cooperating with a ratchet assembly surrounds the blocks. In forming and clamping a frame, frame molding strips are associated with the appropriate framing blocks of the framing form and clamp, the size and number of the strips depending upon the dimension and shape of the desired frame. The belt is tightly wound around the framing blocks to secure the strips while the corners of the adjacent strips are permanently connected to form the frame.
