Product Overview

The gaps between a Fire Door and its frame need to be 2 to 4mm in width to ensure that both the door can close smoothly and that the fire cannot spread through the gap of the fire door. Our Fire Door Gap Gauge is a handy tool designed with a clearly marked dark blue "Recommended Door Gap" area and red "Door Gap Not Recommended" area. Quickly tell at a glance if the gaps around a fire door are within the acceptable range.

  • Lightweight and durable plastic body
  • Angular construction ensures no-fuss, intuitive use regardless of architrave
  • Simple insert-and-glance design with clearly marked "Recommended Door Gap" area
  • Ideal companion for the FREE Safelincs Fire Door Inspection Checklist
  • Compact design for easy storage and transport – fits in your pocket!

Please Note: The Fire Door Gap Gauge is not calibrated and may vary by ±0.5mm. A more careful examination with calibrated measuring equipment may be necessary if any gap just meets either edge of the "Recommended Door Gap" area.

Pretty clear range although the certification gives a plus minus so would recommend some kind of indicator
