FAS Fire Door Gap Gauge

FAS Fire Door Gap Gauge | Stainless Steel Fire Door Gap Measuring Tool

The FAS Fire Door Gap Gauge is a precision measuring tool designed to accurately check the gap between a fire door and its frame. Manufactured from precision laser-cut stainless steel, the set includes four flat shims that can be used individually or combined to measure gaps between 2mm and 4mm.

Unlike wedge-style gap gauges, the flat shim design does not force the door gap open during measurement, helping provide a more accurate reading. Each shim measures 60mm wide, allowing measurements to be taken across a larger section of the door where gaps can naturally vary.

Supplied with a lanyard for convenient carrying, the FAS Fire Door Gap Gauge is a simple solution for measuring fire door clearances.
