Frequently asked questions

How does this compare to the smaller 100mm and 200mm version?

This sign covers the larger 150mm to 400mm size range, for doors or viewing distances where a bigger sign is needed. A compact 100mm-200mm version with the same wording is also available.

What sizes are available?

Three sizes: 150mm x 200mm, 200mm x 300mm and 300mm x 400mm.

Which material holds up best on a heavily used fire door?

Vinyl Composite is the most durable option and is also the only material with channel fixing, useful if the door sees frequent traffic.

Is channel fixing available on all three sizes?

Yes. The Vinyl Composite option has horizontal and vertical channel fixing at 150mm x 200mm, 200mm x 300mm and 300mm x 400mm.

Why pick the photoluminescent version?

It charges under normal ambient light and stays visible if the power fails or the area goes dark, which is useful on doors along an escape route.

What does the sign actually say?

It reads 'Fire door' on the first line and 'keep locked' on the second, in white text on a blue mandatory-sign background.

How is it fixed to the door?

Self-adhesive vinyl sticks directly to a clean, flat surface. The PVC and photoluminescent options are drill-fixed. Vinyl Composite adds channel fixing for posts, frames or barriers.
