The clamp has holes with specific diameters meeting requirements of fastening and mounting. A semicircular cutout on an open end of the clamp provides fastening to posts of different dimensions and to posts with oval mounting hole and fastening hole on a back side. The fastening on a road signal post is made by tightening of screws going through the holes of extended D-shape on a back side of the clamp, and the holes of a road sign board. |
