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 for easy use thanks to the clearly marked dark blue "Recommended Door Gap" area.

  • Lightweight and durable plastic body
  • Angular construction ensures no-fuss, accurate readings
  • Simple insert-and-glance design with clearly marked "Recommended Door Gap" area
  • Compact design for easy storage and transport – fits in your pocket!
