5000 Series Rackmount Cases provide a balance of rugged durability, compactness and effective shock and vibration protection. The FRP (Fiberglass Reinforced Thermoset Composite) material used in these rackmount cases allows great design flexibility for military and industrial electronic applications. Compression molded FRP parts have 65% glass fiber reinforcement in a thermoset polyester resin base, and they are extremely impact resistant.

Rackmount cases were invented and patented in 1965 by Dennis Becklin, CEO of ECS Composites. The original 3000 Series rackmount cases evolved into additional styles of FRP rackmount cases to satisfy the needs of unique applications. 2000 Series cases are extremely compact, rigid rackmount cases with no shock mounts. 5000 Series rackmount cases provide protection for electronic equipment of normal fragility. 6000 Series rackmount cases are used for unusually fragile equipment.
