Frequently asked questions

What does this sign mean?

It's a mandatory instruction telling anyone approaching the door that it must be kept locked shut at all times - commonly used on fire and compartment doors to help contain fire, smoke and heat.

Is this the same as a "Fire door - Keep locked shut" sign?

It carries the same instruction with simpler wording - "Keep locked shut" - and is used in exactly the same way, on any door that must stay locked shut.

What sizes are available?

100mm x 100mm and 200mm x 200mm - pick based on how far away the sign needs to be read.

Which material suits an exterior door?

Rigid PVC, foam PVC or vinyl composite are all suited to outdoor fixing; self-adhesive vinyl is best kept to a smooth indoor surface.

Can it be fixed to a door frame or post instead of the door face?

Yes - the 200mm Vinyl Composite option is also available with a horizontal or vertical channel fixing, suited to metal frames, posts or barriers, as well as flat drill-fix mounting.

Why would I need the photoluminescent version?

It charges under normal lighting and stays visible in a power cut or sudden darkness, useful on doors along an escape route.

What kind of buildings is this sign used in?

Any building with doors that must stay locked shut, including hotels, warehouses, apartment blocks, commercial kitchens and laboratories.
