Inspection gauge for door clearances and flatness, designed to deliver clear, repeatable readings during site checks. Fast, pocket-ready measurements give tradespeople the confidence to mark jobs complete with fewer returns. How well does AOROPS Door Gap Measuring Tool perform for regulation-led fire-door inspections?
⚡ At a Glance
- • Measurement Accuracy: Vernier layout and clear markings simplify on-site readings for routine checks
- • Best for: Site inspectors, joiners and fire-door testers checking clearances and flatness
- • Not ideal for: Measurements that require finer than 0.5mm resolution
Vernier feeler gauge designed for door gap, width and flatness checks. Compact construction and a lanyard make it easy to carry on site.
Reliable regulatory checks – with vernier feeler gauge design
Vernier construction separates the main scale from a fine-reading vernier, allowing users to read smaller increments more clearly than a single straight scale. Clear etched graduations reduce ambiguity when comparing values during inspections.
Accurate gap readings help meet fire-door clearance requirements, reducing the risk of failed inspections and rework.
Portable site use – thanks to compact size and lanyard
Compact dimensions of 152 × 17 × 15 mm and a lightweight build at 84 g combine with a handle lanyard for secure carrying. The shape suits pockets and tool-belt loops for immediate access during rounds.
Quick access on-site speeds up routine checks and keeps the gauge to hand during multi-room inspections.
Versatile measurement capability – with wedge-shaped profile and clear scale
Wedge-shaped vernier feeler geometry allows slipping the gauge into narrow gaps, while the clear scale covers a measurement span and a defined accuracy. The layout supports gap, thickness and flatness deviation checks.
Useful for door undercuts, thickness checks and flatness assessment across house and engineering inspections.
