Fire Door Gap Measuring Tool

This project have identified the need to accurately measure the gap around fire doors.

It is common practice to use a 3mm packer, however a packer is not calibrated and will not measure the door gap behind the front face of the door or frame.

Often door frames are installed with packers to ‘twist’ the legs of the frame that give the illusion of a 3mm gap but in reality the gap where the intumescent strip or smoke seal is located may be 4mm or greater.

In order to correctly measure the gap over the width of the door or frame they have manufactured a measuring tool.
