This listing is for a set of four (4) vintage angle clamps from the Adjustable Clamp Co., also known as Jorgensen. These heavy-duty clamps, model No. 9133, are proudly made in the U.S.A. and feature patent number 3,072,396. Ideal for woodworking, framing, and various joinery projects, these clamps allow for precise holding at angles. Each clamp is constructed from durable cast metal, likely aluminum, with steel screw mechanisms. They show signs of age and use, including cosmetic wear, scratches, and some surface rust on the steel components, all consistent with their vintage nature and functionality. A perfect addition for any workshop or collector of quality vintage tools.
