SKB's innovative line of ATA Removable Fly Racks have revolutionized the way you travel and protect delicate electronics. Now available in a 6U Shock Rack model! Our internal Fly Rack frames are made in Orange, California, and are built of high strength, lightweight aluminum alloy and 11 gauge hot rolled carbon steel rack rails—just like SKB Military Grade Shock Racks. The internal frame of the 3i-2424-146U contains front and rear rack rails with a 19'' rack depth. ABS plastic covers the top and bottom of the removable shock rack for added protection when the rack is out of the case. The rack frame easily fits into SKB's iSeries case and is protected by high quality PE foam that provides space for protruding knobs and buttons. Convenient in-line wheels and push button release pull handle enable easy transport. iSeries injection molded waterproof cases are constructed of ultra high-strength polypropylene copolymer resin and feature a waterproof, submersible design (IP67) that is resistant to corrosion and impact damage. Molded-in hinges, TSA acceptable trigger release latches, comfortable snap-down rubber over-molded cushion grip handle, secure stacking, and automatic ambient pressure equalization valve (MIL-STD-648C) all contribute to their military grade design. Exterior dimensions: 67,31 x 67,31 x 39,75 cm.
