Featuring our New Arrival, the One Stop Fire.Shop Spider Gauge. 
Our Fire Spider Gauge is a high-tech, compact measuring tool used to quickly check the compliance of fire door gaps. 
 
In the UK, regulations state the gaps between a fire door and its frame should measure between 2mm and 4mm which is stated across the product. 
 
Available in all 5 colours, this spider gauge allows inspectors to seamlessly the different legs or edges of the gauge into the door clearance to confirm if the gap is compliant. 
 
Its a must have for all contractors and fire safety inspectors.
 
MEASURE ONCE. KNOW FOR SURE.
