I wasn’t sure whether you take the reading from the narrow side or wider side of the slider as it doesn’t tell you on the device or packaging - an experienced fire door inspector, who uses a similar tool, told me it’s the measurement on the narrower side that’s relevant, i.e, the side of the slider that touches the door/ frame. Very easy to use and good value for money. I bought this one another wider one, shaped more like a credit card - using both helps confirm accuracy of the readings I found. Happy overall although I feel clear user instructions would be useful. Review: Great for measuring door margins. - Used these on a job with very strict regulations on fire doors, very accurate and fits easily in your pocket or tool belt, a must with high end finish jobs. 👌🏻 Found the best way to use it is have the slider set away from the door margin until its inserted then slide it to the door for a more accurate read. ## Features - 【High-quality material】Door gap measuring tool is Made of high-quality materials, the scale is clear and easy to identify, durable, not easy to damage, and can be used for a long time. - 【Easy to carry】The size of the feeler gauge is 152 × 17 × 15 mm and the weight is 84g, which is small and light in weight, and has a lanyard on the handle for easy portability - 【Vernier feeler gauge】The fire door gap gauge checker tool has a vernier design, which can easily read the measurement results, and is an ideal measurement tool in your engineering inspection projects. - 【Clear reading】The measuring range is 1-15mm, and the accuracy is 0.5mm.

I can probably improve it by grinding the back surface carefully. ## Frequently Bought Together - Door Gap Measuring Tool, 1-15mm Fire Door Gap Gauge Checker Tool Engineering Ruler, Feeler Gauges for House Engineering Inspection Flatness Measuring Tool Ruler(0.5mm/0.2mm) (0.5mm) - Fire Door Gap Gauge Checker Tool, Small and Light, Pocket Fit - Rolson 60515 2 LED Telescopic Inspection Mirror --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vu/products/498600377-door-gap-measuring-tool-1-15mm-fire-door-gap-gauge](https://www.desertcart.vu/products/498600377-door-gap-measuring-tool-1-15mm-fire-door-gap-gauge) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-05*
