This Fire Door Gap Gauge is the perfect tool for anyone who inspects fire doors as part of a fire risk assessment or as the fire responsible person. It is a lightweight and compact item, that clearly shows if the fire conforms with the recommended fire door frame gap of 2-4mm, with its distinctive blue panel. 

Designed using lightweight but durable plastic, the angular design allows accurate and clear measuring, it’s a must-have item for anyone who has recently completed a Fire Door Inspection course or Responsible Persons for Fire Training.

Why do Fire Doors have a recommended door frame gap?

Fire doors have a recommended door gap of 2-4mm to allow the door to open easily and smoothly but also to prevent smoke from leaking through the gap in the event of a fire starting. This fire door gap gauge gives an easy-to-see visual of your door gap measurement and shows you if your door complies.
