This 4300 Wheeled Hard Case from HPRC has a 23 x 12.6 x 12.2" interior capacity and is designed to protect contents from impacts, moisture, dirt, and corrosion. It has a lid handle for one-handed use with lighter loads, and two side handles to safely lift and carry heavier loads. The case is made from polypropylene, fiberglass, rubber, and stainless steel and is ATA 300, IP67, STANAG 4280, and DS 81-41 complaint. When closed, the interior is fully sealed to keep dust and water out. It is submersible to 3.3' and provides long-lasting resistance to wear-and-tear.
The ergonomic carry handles can be folded away to reduce the amount of space the case occupies. The case is securely closed with four double-hinged latches, and the base and lid are connected by a pair of heavy-duty hinges.
Both the base and lid include a pair of shackle eyelets that align when the case is closed and two separately-available padlocks can then be used for enhanced security. A built-in valve automatically equalizes air pressure between the interior and exterior of the case. This keeps the case securely closed during air travel or when moving from areas of low altitude to high altitude.
