NSN 8145-01-615-8257 7U Shock Rackmount Case

Removable Shock-Isolated Frame for 7U Rack Equipment

The SKB 3RR-7U24-25B combines a rugged rotomolded LMDP polyethylene shell with a shock-isolated internal rack frame. Eight elastomeric shock absorbers help reduce the shock and vibration transmitted to properly installed equipment during compatible transport and handling conditions.

Unlike the static-frame 3RS version, the 3RR model uses a positive-lock removable frame. The rack slides outward like a file drawer for access to installed components and can be removed completely for bench integration, equipment mounting, wiring, inspection, and maintenance.

The 7U frame provides approximately 12.25 inches of vertical mounting space for compatible standard 19-inch equipment. Square-hole front and rear rails accommodate compatible #10-32 or 6 mm cage nuts, allowing the rack hardware to be configured for the equipment package.

The standard shock configuration is published for 40 to 150 pounds of installed equipment. An optional 160-to-300-pound configuration requires additional shock absorbers installed by SKB. The correct configuration depends on total equipment weight, center of gravity, front-to-rear balance, vertical placement, support requirements, and the transport environment.

Standard features include gasket-sealed removable lids, recessed black powder-coated stainless steel hardware, eight spring-loaded lift handles, an automatic pressure-relief valve, lid hangers, molded stacking ribs and lugs, coupling straps, and built-in edge casters. The manufacturer states that the case meets or exceeds MIL-STD-810H; confirm any contract-specific test method, environmental requirement, ingress rating, or certification before procurement.

Rackmount Integration and Configuration Options

Cases2Go provides equipment integration services for applications requiring installed electronics, horizontal support rails, connection panels, cable management, power distribution, labeling, accessory storage, or other application-specific components.

Options for the SKB 3RR-7U24-25B may include 24-inch support rails, load spreaders, additional rack hardware, a shipping-label plate, accessory pouches, the factory-installed heavy-payload configuration, and the compatible 3RR-RCB caster board. Accessory compatibility and payload effects should be confirmed for the complete configuration.

Provide the equipment manufacturer and model, rack-unit requirement, chassis depth, installed weight, center of gravity, mounting information, connector locations, cooling requirements, cable-routing plan, power requirements, transportation environment, and any available drawings. Cases2Go can help determine whether the SKB 3RR-7U24-25B is suitable for the complete equipment package.
