Purpose-built protection

The SKB 3I-2918-14BE is an empty injection-moulded waterproof case built to MIL-C-4150J and MIL-STD-810F standards. Its ultra high-strength polypropylene copolymer resin shell resists corrosion, impact, UV, solvents and fungus. A gasketed seal makes the case submersible, while an automatic ambient pressure equalisation valve compliant with MIL-STD-648C protects contents during altitude or temperature changes.

Upgrade from soft bags

This case replaces fabric duffels or unsealed hard cases that let in water, dust or crush under load. The jump is worth it when gear must survive submersion, rough handling or pressure swings during transport. The patent-pending trigger-release latch system and moulded-in hinge keep the lid secure without the fail points of traditional clasps or external hinges.

Capacity and limits

The 29 x 18 x 14 inch interior accommodates rifles, camera kits, drones or avionics with room for custom foam inserts. Integrated wheels and a snap-down rubber over-moulded handle ease movement of heavy loads across tarmac or rough ground. Buyers needing a smaller footprint, lighter carry weight or a case without wheels should look elsewhere.
