SKB Cases 3SKB-R904U28, 28-Inch Deep 4U Roto Shock Rack Case

Description

The SKB Cases 3SKB-R904U28, 28-Inch Deep 4U Roto Shock Rack Case feature a depth of 29.5″ from front to rear rail, with lid depths of 4.5″ per lid to accommodate deeper servers. They also include a revolutionary new patented Adjustable Rail Conversion System (ARCS). This ARCS technology allows the user to adjust the rack width up to 0.5 inches on each side. Optional easy-mount adapter rails will convert the equipment mounting standard from 3/16″ threaded to 7/32″ through holes or square cage nut windows. The 7/32″ through hole option and the 3/16″ threaded are special order items. 28″ 3SKB Roto Shock Racks will accommodate Dell and Compaq servers utilizing “Versa-rail” or “Rapid-rail” pull-out systems.

All 3SKB Series Roto Shock Racks feature a compound hinge system that allows the lid to swing out and completely around to lie flat against the main body of the case. This also enables effortless removal/reinstallation of the lid with a simple lift motion. Both front and rear lids are designed to protrude into the base of the case approximately 1″ with a unique double wall structure that makes them incredibly rigid where this intersection occurs, providing MIL-SPEC sealing characteristics with significantly fewer latches than most competitive cases. This revolutionary design allows for rapid deployment in an up-right configuration, even when stacked — 3SKB Roto Shock Racks are the only shock racks in the marketplace today that will open front and back while stacked.

The inner rack chassis is built of high strength / lightweight aluminum alloy and 11 gauge hot rolled carbon steel rack rails to DIA-310 standards, creating an H-shaped frame that provides maximum strength. Shock and vibration mitigation is accomplished with eight (8) elastomeric isolators rated for a payload range of 40 – 150 pounds in a standard configuration, and up to 300 pounds in a special order extended payload configuration allowing adequate sway space for ambient air circulation and heat dissipation. The rack rails come pre threaded for standard 10-32 hardware and mounting screws are included.
