The shallow racks case are roto-molded for strength and durability and feature a new exterior design with interlocking capabilities, recessed steel, mil-spec black twist latches, shock absorbing rubber feet and new heavy-duty flush handles. With the addition of rear rack rails and the new cover design, the depth on the new Roto–molded shallow racks has been extended to 10.7” from front to rear rail. Gear can now be mounted front and rear with the supplied rackmount clips. The re-designed Roto-molded shallow rack cases meet the needs of musicians and pro audio engineers. The new 1SKB-R3S now has a full front and rear cover instead of a rear access panel for easy access. Both doors have a rubber gasket to keep water out of the case.
