Frequently asked questions
Can I use the 518 plate on its own?
Can I use the 518 plate on its own?
No. Diagram 518 is a supplementary plate, designed to sit beneath a warning sign - usually Road Narrows Left or Right (Diagram 517). On its own it gives drivers no warning context, so always pair it with the main face.

It measures 725mm long by 275mm high on a 3mm plastic backing board, with 300mm hole centres.
Will it fit the frames I already own?
Will it fit the frames I already own?
It is drilled on 300mm hole centres, which suits our mini quick-fit frames. Check the toggle centres on your existing frames before ordering; custom hole centres are available if yours differ.
Is this plate legal for road use?
Is this plate legal for road use?
Yes - it conforms to Chapter 8 of the Traffic Signs Manual and The Red Book. Follow current government guidance on placement when setting out your works.
How reflective is it?

The face is printed on RA1 (Class 1) engineering-grade prismatic sheeting, intended for lower-speed roads such as urban streets, residential areas and local roads.
Does it come with a frame or fixings?
