Frequently asked questions
Is this the same as a fire door sign?
Is this the same as a fire door sign?
It carries the same mandatory blue and white format as our fire door signage, but reads simply "Keep locked" rather than naming the fire door specifically - suited to any door, not just a fire door.
What sizes are available?
What sizes are available?
150mm x 200mm, 200mm x 300mm and 300mm x 400mm - the three sizes share the same five material and fixing options.
Which material suits an exterior door?
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 I fix it to a gate or barrier post rather than a door?
Can I fix it to a gate or barrier post rather than a door?
Yes - every size is available in Vinyl Composite with a horizontal or vertical channel fixing, suited to posts, barriers and gates as well as flat drill-fix mounting.
Why choose the photoluminescent version?
Why choose the photoluminescent version?
It charges under normal lighting and stays visible if the power fails, useful for corridors and stairwells during an evacuation.
Does the sign name what's behind the door?
Does the sign name what's behind the door?
No - the wording is a general "Keep locked" instruction, so it works on any door requiring access control, not just fire doors.
How is it fixed to the door?
How is it fixed to the door?
Self-adhesive vinyl sticks directly to a clean, smooth surface; the other materials are supplied with drill holes, and the Vinyl Composite option is also available in a channel format for all three sizes.
