Road Narrows Right quick-fit sign face - Diagram 517R
The Road Narrows Right sign face warns drivers that the carriageway ahead narrows from the right-hand side. It is a face-only board for temporary traffic management: printed on RA1 Class 1 engineering-grade reflective sheeting over a 3mm plastic backing, conforming to Chapter 8 and The Red Book, and made in the UK. It drops into a quick-fit frame (sold separately) on 300mm hole centres.

Pairing and set-out
On site this face is commonly run with the Single File Traffic supplementary plate (Diagram 518) mounted beneath it, and Chapter 8 also calls for Men at Work signing on the same works. Check current government guidance for exact placement and spacing.
Fixing and compatibility
This listing is the sign face only - quick-fit frames are sold separately. The 300mm hole centres line up with our mini quick-fit frames; check the toggle centres on your existing frames before ordering, as some faces can be drilled with more than one set of holes.
