Designed as watertight/crush-resistant armor for handheld electronics and any small, delicate items, the case sports a high-impact, heat and chemical resistant polymer shell that will stand up to some of the harshest conditions known to man. As additional protection, the 1170 Pelican case features stainless steel hardware and double-throw latches that can stand up to 400 pounds of pull force, yet open with a light pull. The case’s tongue-and-groove lid construction and polymer o-ring creates a watertight seal and its built-in, automatic pressure equalization valve keeps moisture out and makes it easier to open the case at any altitude.
