ABSTRACT:
A rebar clamp for clamping rebars to templates during the pouring of footings and the like is disclosed. The disclosed rebar clamp includes a body in the form of a helical coil and a screw member threadedly engaged with the helical coil and having a transverse handle at its outer end. A pair of arms are affixed to the opposite sides of the helical coil and are spread wide enough apart to embrace a template of well known type across its major dimension. The outer of each arm is provided with a hook which can tightly engage a rebar and firmly clamp it against one major face of the template when the screw member is rotated in such manner as to advance it against the opposite major face of the template.
