Questions?
Find answers to common questions about our products, materials, and ordering.
Our Standard range uses durable PETG plastic, ideal for everyday use. Our Professional range features carbon-fiber reinforced ASA for superior strength and UV resistance in demanding environments.
Insert packs are footprint-specific: 5x4 packs fit 5x4 boxes and 6x7 packs fit 6x7 boxes. Within each footprint, you can mix layouts across Standard and Professional tiers.
Absolutely. Our insert packs come in several pre-designed layouts (Starter, Fastener, Electronics, Craft), but you can also purchase individual boxes and create custom arrangements to suit your needs.
Professional boxes with carbon-fiber reinforcement offer superior impact resistance, UV stability, and temperature tolerance compared to Standard boxes. Ideal for mobile workshops, outdoor storage, and high-use environments.
The Starter Bundle includes a complete 5x4 storage box with a mixed layout insert pack containing small and medium bins, giving you immediate organisation solutions.
For bulk orders or wholesale inquiries, please contact our team at hello@graphitemodular.co.uk with details of your requirements.
"U" (Units) refers to the height of the storage box. We offer four heights: 6U (baseline, compact), 9U (taller for more storage), 12U (deep, for larger items), and 15U (extra deep for maximum capacity). Choose based on what you need to store—smaller items work well in 6U, while tools or tall supplies need deeper units.
We offer both 5x4 and 6x7 Gridfinity-compatible footprints, each available in 6U, 9U, 12U, and 15U heights. For external measurements used in planning or fit checks, use the product specification details listed on each SKU page.
Yes! You can stack and combine any height variants. Many customers use a 6U box for quick-access items and a 12U below for larger storage, creating a custom organisation system.
