Inspection tool for door gaps that promises clear, repeatable measurements and simple on-site use. Confidence for inspectors and handy reassurance for homeowners during safety checks. Is the Jetisva Fire Door Gap Gauge precise and sturdy enough for regular inspection work?
⚡ At a Glance
- • Measuring Accuracy: 1–15mm measurement range with vernier-assisted reading and 0.5mm precision
- • Best for: Building inspectors, engineers and DIYers checking door gaps and plane deviation
- • Not ideal for: Measurements outside the 1–15mm range or jobs requiring electronic readouts
Wedge-shaped vernier feeler gauge set for checking door gaps between 1 and 15mm with 0.5mm precision. Supplied as a two-piece, metric-marked set aimed at inspection and DIY tasks.
Accurate gap reading - with vernier scale and dual-marked metric scale
A vernier scale enables interpolation between main scale marks, delivering readable increments down to the stated 0.5mm accuracy across the 1–15mm span. Dual-marked metric graduations help confirm measurements quickly without conversion.
Clear, repeatable readings make compliance checks faster and reduce the chance of mis-measurement during inspections.
Robust on-site performance - with zinc alloy construction and ergonomic handle
Zinc alloy construction gives strength and resistance to wear while a moulded plastic, non-slip handle improves grip during use. A supplied non-slip cord keeps the gauge secure on site.
Durable build and a firm grip reduce damage risk and keep measurements reliable across repeated site use.
Versatile mounting and use - with M6 screw hole and wedge-shaped form
An M6 threaded hole allows attachment to diagonal rulers or telescopic rods for extended reach or hands-free positioning. The wedge shape is suitable for assessing width, gap and plane deviation in a single pass.
Easy to adapt for different inspection setups, making the set useful for both professional surveys and home DIY checks.
