What material is the box made from?

It’s constructed from impact-resistant ABS plastic with a silicone O-ring seal and stainless-steel hinge pins.

What waterproof rating does it have?

The box is rated IP67, meaning it’s fully dust-tight and can withstand immersion in up to 1 meter of fresh water for 30 minutes.

Will it protect against saltwater and other liquids?

While the IP67 rating covers fresh water immersion, prolonged exposure to saltwater may cause corrosion of metal parts. Rinse with fresh water after saltwater use and dry thoroughly.

How do I open and close the box?

Simply lift the latch on the front; the hinge pops open smoothly. To close, press down firmly until you hear a click, indicating the silicone seal is fully engaged.

Is the interior cushioned?

The base comes with a removable thin EVA foam pad to protect fragile items. You can cut it to fit the shape of your gear.
