Description

SKB 7U Removable 20 Inch Deep Shock Rack

SKBs 3RR Series Removable Shock Rack are lightweight, shockproof, watertight, dustproof, heat and chemical resistant, perfect for protecting and transporting your sensitive electronic equipment. Molded of LMDP Linear Medium Density Polyethylene plastic that meets or exceeds MIL-STD 810G standards, these Shock Racks also include 8 elastomeric shock absorbers which allow for a standard payload range of 40 to 150 lbs (optional extended payload range of 160 to 300 lbs can be accommodated as a special order option). The 20 in. 3RR Series Removable Racks are 20 inches deep from rail to rail with a standard 19 in. rack width per ANSI/EIA-310-C specification and feature square-hole rack rails to accommodate either #10-32 US standard or 6mm International standard cage nuts which are supplied with the cases.

The rugged roto-molded shell ensures industry leading strength and impact resistance. The standard commercial off the shelf (COTS) case comes with 2 in. deep front and rear lids to accommodate rack gear that is longer than 20 inches. Molded-in stacking ribs and lugs are designed to stack with all SKB 3RR and 3RS cases, as well as competitive manufacturer cases, and feature black powder coated stainless steel hardware that is recessed for protection and 4 comfort grip spring loaded lift handles which allow for easy movement. An automatic pressure relief valve is another standard feature along with gasket sealed lids that include convenient lid hangers to store your lids when your equipment is in operation. Coupling straps are included for securing the racks together when stacked.

The interior of the case features a removable rack with a patent pending positive lock latching system that slides open like a file drawer, allowing full access to racked equipment. The interior rack is also completely removable allowing complete frame access for bench integration.

The 3RR-7U20-22B is a practical choice for larger portable rack systems that require additional vertical space for more advanced equipment layouts. Its 7U configuration supports expanded system builds while retaining the convenience of a removable rack frame.

Note: 3RR 20 in. Shock Racks do not come standard with wheels.
