FAS Fire Door Gap Gauges

A set of 4 precision laser-cut stainless steel shims for measuring the gap between a fire door and the frame. The 60mm width allows for an accurate measurement as the gap can vary across smaller lengths. The flat shim design prevents the gap from being opened up further which can be a drawback of wedge style gauges.

Features and Benefits

• Mix & match thicknesses to achieve 2-4mm gap size
• 60mm width for accurate measurements
• 0.5, 1.0, 2.0 & 3.0mm shims
• Corrosion-resistant stainless steel

Gaps around the top and sides of fire doors should be less than 4mm when the door is closed.
