SKB 5U Half Width Rack Case (20" Deep) 3RR-5U20-HR

Notify me when this product is available:

This standard commercial-off-the-shelf (COTS) case comes with a removable 4” deep front lid and 1” deep rear lid, as well as a built-in retractable pull handle, wheels, and 4 comfort grip spring-loaded lift handles for maximum portability.

The interior rack features SKB’s patented “positive lock” latching system that slides open like a file drawer, allowing easy access to racked equipment. The rack can also be fully removed providing complete frame access for bench integration. Like all 3RR Series Shock Racks, this half rack is molded of LMDP Linear Medium Density Polyethylene plastic that meets or exceeds MIL-STD 810G standards. It comes standard with 8 elastomeric shock absorbers which allow for a standard payload range of 40 to 150lbs. The rugged roto-molded shell and black powder coated stainless steel hardware (recessed for protection) ensure industry leading strength and impact resistance, while its compact size makes it highly portable and easy to deploy. Additionally, the molded-in stacking ribs and lugs are designed to stack with all SKB 3RR and 3RS shock racks—as well as competitive manufacturer’s cases—making this the perfect complement to any collection of racked equipment.


SKB 3RR Shock Racks are available in custom colors and other customization options (hardware, built-ins, expanded payloads, etc.)  Contact us here for more details.
