4U SKB Removable Roto Shock Rack (24 RD)

The SKB 3RR-4U24-25B is a 4U shock-mounted rack case built for touring and rental crews moving smaller rack systems — DI boxes, wireless receivers, small mixers — that still need case-level shock protection. Its 24-inch rail-to-rail depth matches SKB's other 3RR cases, so it shares hardware and stacking compatibility across a whole fleet of case sizes. It's built on the same roto-molded, MIL-STD-810G-rated platform as the rest of the 3RR line.

• Shock-isolated interior: 8 elastomeric shock absorbers support a standard payload of 40-150 lbs (extendable to 160-300 lbs as a special order).
• Military-rated shell: Roto-molded Linear Medium Density Polyethylene shell meets or exceeds MIL-STD-810G for impact resistance.
• Standard rack fit: 24" rail-to-rail depth, 19" rack width per ANSI/EIA-310-C, with square-hole rails accepting #10-32 US or 6mm international cage nuts.
• Slide-out removable rack: Interior rack slides open like a file drawer with a "positive lock" latch and can be fully removed for bench integration.
• Field-ready hardware: 8 spring-loaded lift handles, an automatic pressure relief valve, gasketed lids with lid hangers, and recessed stainless hardware.
• Stackable design: Molded-in stacking ribs/lugs and included coupling straps allow secure stacking of multiple cases.
