SKB revolutionized the industry with the first INJECTION molded guitar case! To accommodate a wider variety of body shapes they have developed the iSeries 5014-OP Open Cavity Electric Bass case. iSeries injection molded waterproof cases are constructed of ultra -high-strength polypropylene copolymer resin and feature a gasketed, waterproof, submersible design (IP67) that is resistant to corrosion and impact damage. Its molded-in hinges, patented ''trigger release'' latch system with TSA recognized and accepted locks, four reinforced locking loops for customer supplied locks, comfortable, snap-down rubber over-molded cushion grip handles, secure stacking, and automatic ambient pressure equalization valve (MIL-STD-648C) all contribute to its military grade design. The plush platinum interior provides total neck support and protection on all sides.
