SKB Portable Race Case for tour / road gig. SKB portable rack cases are designed with three things in mind: toughness to handle even the harshest handling conditions, light weight for easy portability, and innovative design to give you the best possible product to protect and transport your valuable gear. The SKB line of stackable racks has received worldwide acclaim for durability, convenience and easy handling. Made of ultra high molecular weight polyethylene, they are less than half the weight of old fashioned wood racks and provide maximum protection. An internal frame mounted on coiled shock absorbers on all 8 corners. These revolutionary shocks are designed to control the effects of shock & vibration on three axes. The "sway" space around the internal frame provides natural air conditioning... very important for delicate audio equipment. Used case had a crack on handle that I reinforced and epoxied. Does not effect the case at all (except for the looks!) Original price was over $500.
