Full description


The Rhino Waterproof Military Hard Case is a Rifle Case made from very tough Polypropylene (PP) and Glass Fibre mix material which is the secret to its' Impact and Extreme Temperature resistant design, but is also a lightweight compound that makes this Case easy to move around. The external design of the Case is such that it is very easy to stack multiple Cases together, and a set of Integrated Wheels and Grab Handles makes them very easy to manoeuvre about. Inside the Case is a Pick and Pluck Foam layer, meaning you can cut out slots for your equipment to sit in, and stop them moving about in transit. The edge of the Case has a Rubber Seal that protects the contents from the ingress of Water (1m up to 30 minutes) and Dust. A Pressure-Relief Valve can also be found to control the internal Pressure of the Case without compromising the Waterproof Seal.

The case comes with multiple foam layers designed to keep you valuables safe and secure during movement. The lid of the case features egg shell foam to prevent the contents from sliding when closed, and a foam separator piece on the bottom of the case. The case also comes with a thick pick and pluck layer, allowing you to customise the shape of the foam to achieve the perfect fit around your precious valuables. The panel is cut and separated into cubes which can be pulled out to create the shape of the item you want to store inside, preventing the contents from sliding around inside the case and keeping them even more safe. Pick and Pluck foam is perfect for those who want to store lots of small items in once case without worry of them sliding into each other and causing damage, such as a large collection of Scopes and Magazines sat next to your Rifle.

The case is fully IP Rated and tested by a 3rd party quality assurance company to give you the confidence you need to put your trust in the case, tested for Waterproofing, Impact Resistance, Immersion, and Temperature Tests. The case is IP rated IP67, meaning that the case is fully dust tight and waterproof, making it great for transporting electronics as well as sights and scopes. The case can be submerged in water up to 1m for 30 mins meaning that you don't have to worry about rain or splashes during transport, and your equipment will come out as dry as when you put it in there. The case is tested for temperatures between -40°c and 90°c allowing the case to remain strong no matter the weather conditions.

The case features heavy duty clasps designed to keep the case secure, with four strong dual movement clasps which make the case easy to open, but give an extremely strong lock for transport. If you're worried about tampering the case also features two pad-lock holes, allowing for both standard padlocks to be used as well as TSA approved locks, allowing the case to be used for transport on Airlines. The case is secure enough to make it enough of a challenge for anyone trying to get a sneaky look inside.

The case also features an adjustable air valve which is designed to release pressure for transport by air, or in situations with high pressure such as at height. The valve is fully adjustable, but also water resistant, allowing you to adjust the amount of pressure allowed to equalise inside the case but without flooding the contents.

Whether you need to safely transport, store or protect your Firearms, or you're looking for a Hard Case that can fit a huge variety of kit inside, whilst also protecting the contents from everything the environment has to offer, then the Rhino Waterproof Military Hard Case is the one for you.
