ABSTRACT:
A double C-clamp device is provided which consists of a pair of C-clamps, each having a fixed jaw and a moveable jaw and a pair of clamp bars. A fastening structure is for attaching the first clamp bar transversely between the fixed jaws and the second clamp bar transversely between the moveable jaws of the C-clamp. The C-clamps which are in a stationary spaced apart relationship can cause the clamp bars to come towards each other to hold a work piece which may be tapered an have irregular shaped contact surfaces.
