520 dual carriageway ends sign face for highways and permanent site use
The 520 sign warns drivers that a dual carriageway section is coming to an end, with the two lanes merging back into a normal two-way carriageway. It looks similar to the road narrows sign, but the 520 sign shows the merging lane lines joining directly with no gap between them, rather than each lane narrowing on its own. This permanent sign face is manufactured to BS EN 12899-1:2007 and UK highway regulations, CE marked, with a Class 2 RA2 high-intensity reflective face for clear visibility at night and in poor weather. It is supplied as the sign face only, in wall mounted or post mounted options across three sizes.

Mounting options
Post mounted faces arrive with rear channels already fitted, so they clamp straight onto a post and lock in place with anti-rotational clips - the face cannot twist out of position once fixed. Posts and clips are sold separately, with two clips needed per sign. Wall mounted faces are supplied plain with no holes, so the aluminium composite can be drilled for screw fixing or bonded in place with a no-nails adhesive.
