60mph quick-fit sign face - diagram 670 roadworks speed limit
This 60mph sign face is the diagram 670 speed limit roundel for temporary traffic management, used where roadworks reduce the normal limit on motorways and dual carriageways. It is printed on RA1 engineering grade reflective sheeting over a 3mm plastic backing, conforms to Chapter 8 and The Red Book, and is made in the UK. This listing is for the sign face only - quick-fit frames are sold separately.

Frames and fitting
The face has 300mm hole centres, so check they match the quick-fit frames you already run before ordering. Some faces can be drilled with both sets of holes for compatibility with different frames, and a ballast weight keeps the frame stable in wind. For placement, follow the current government guidance for the road type and speed.
