HPRC Blue Wheeled Hard CasesThese HPRC Blue Wheeled Hard Cases are lightweight, waterproof, and unbreakable. They are also crush, acid, and corrosion proof and meet ATA 300 specifications for transit cases. The interior is cubed foam that can be configured to accommodate your gear. Our HPRC Blue Wheeled Hard Cases are made of a hard resin shell that is virtually unbreakable. The interior O-rings keep the case air and watertight. They also feature a smooth low-profile backing that houses a high-strength aluminum telescoping handle. This efficient design translates into a clean finish on the back side of the case, while the use of the aluminum delivers a stiff feel for complete control between the handle and case. HPRC Black Wheeled Hard Cases have smooth gliding wheels and a soft grip handle for carrying, and an air pressure relief valve. Their ability to stand up to just about anything make them a favorite with the military for transporting valuable photo and video equipment.
