For the ultimate protection of your valuable photography equipment, consider the Wheeled Series 935 Lightweight Nk-7 Resin Waterproof Protective Case. This robust case is designed with a PowerClaw latching system (Us Patent No. 8,297,464), a unique feature of all Nanuk cases, engineered to keep your case securely closed under the harshest conditions. The PowerClaw clamps the case shut with compressive force, while the integrated slide lock ensures the case remains closed during transport or even when dropped, safeguarding your precious items.This case is not only tough but also waterproof, boasting an IP67 rating. This means it can withstand submersion at 3ft for 30 minutes, thanks to the custom-designed waterproofing seal that resists deformation and fatigue, ensuring a long-lasting watertight seal. This makes the Nanuk waterproof cases perfect for demanding applications such as search and rescue, marine transportation/storage, and diving.
