The new 1SKB-R4S rack case now has a full front and rear cover instead of just a rear access panel. Both doors have a rubber gasket to keep water out of the case. The Shallow Racks are roto-moulded 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–moulded Shallow Racks has been extended to 10.7" from front to rear rail, and you can now mount equipment front and rear with the supplied rackmount clips.
