The re-designed Roto-molded Shallow Rack Cases meet the needs of musicians and pro audio engineers. The new 1SKB-R4S 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. The Shallow Racks 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 rack mount clips.
