SKB-R904U20 4U Roto Shock Rack 20" ATA Case

Questions about this product?

The SKB R904U20 4U Roto Shock Rack 20" ATA Case features a 20" deep rack frame installed in a roto molded tough shell with an integrally molded valance. This eliminates the metal valance on the outside of the case, coupled with a rubber gasket on both the front and rear doors for water resistant protection. This case's integrated molded valance, ergonomic handles, and recessed, heavy-duty twist latches allow them to meet most ATA and military specifications.

An internal frame mounted on adjustable Elastomer shock absorbers on all eight corners. These shocks are designed to control the effects of shock and vibration on three axes. The "sway" space around the internal frame provides natural air conditioning. This is very important for delicate audio equipment. This case is half the weight of traditional wooden cases.

This SKB-R904U20 Roto Shock Rack case has the Roto X pattern and is stackable within the series.

  • Standard 19" rack width as per EIA standards with 4 space rack height
  • Meets most ATA and Military specifications
  • Water resistant case
  • Internal frame mounted on adjustable Elastomer shock absorbers on all eight corners
  • Mounting hardware in the racks is easy with the SKB rack rail and provided hardware
