High-visibility face

A black 20 on a white background with a red surround keeps the limit obvious to every driver.

Two fixing options

Post-mounted faces have rear channels for anti-rotational clips; wall-mounted faces drill or bond straight to the wall.

Made in the UK

UK-manufactured 3mm aluminium composite that withstands all weather conditions.

Frequently asked questions

Why 20mph rather than 30mph?

A 20mph limit reduces the severity of a collision and suits places where people and traffic are close together, such as residential streets, school routes and site roads.

Do I need extra repeater signs along the route?

That depends on the layout and length of the road - for public highway schemes, check with the relevant authority on which repeater and terminal signs are needed alongside this face.

How is the sign fixed to a post?

The post-mounted face has rear channels that clamp to a 76mm post with anti-rotational clips, so it can't twist once secured.

What size do I need?

300mm and 450mm suit site and estate roads; 600mm and 750mm give better visibility on faster approach roads or where sight lines are longer.

Is the wall-mounted version pre-drilled?

No, it arrives with a plain back - drill the composite for screw fixing or use a suitable heavy-duty adhesive.

What is the sign made from?

3mm aluminium composite with a grey rear, finished in Class 2 RA2 high-intensity reflective sheeting so the limit stays visible after dark.

How long does delivery take?

Each sign is made to order, so allow 7-10 working days for dispatch.
