SKB 4U iSeries Injection Molded Case with Removable 20 in. Deep Fly Rack with Wheels

Transport your rack gear with confidence in SKB's 3i-2424M103U rolling rack case. It's the perfect solution for flying or shipping delicate equipment. Inside this Fly Rack's rugged polypropylene copolymer resin case is a 3U removable injection-molded shock rack cage. A custom-cut foam interior protects your equipment during transit.

This case features convenient in-line wheels and a push button release pull handle providing easy transport, threaded rails in the front and back with a 20 in. rail-to-rail depth, and molded-in hinges contributing to the case's sleek appearance and add additional protection. Carry-on size has TSA-compliant trigger-release latches providing dependable closure and can be secured with a padlock (See Accessories Tab).

The iSeries case is strong, waterproof, and resistant to dirt, dust, corrosion, and more. Its automatic pressure-equalization valve prevents damage caused by drastic changes in air pressure.

Combining both injection molded cases and racks, with improved waterproof Fly Racks are less than half the weight of standard shock racks and more affordable than previous models -- all without compromising strength or durability.

SKB's injection molded rack frames are manufactured alongside the iSeries cases. Rack frames are removable and fit easily into SKB's iSeries cases, where they are protected by high quality PE foam that provides space for protruding knobs and buttons.

SKB iSeries Injection Molded Mil-Standard Waterproof Cases are molded of ultra high-strength polypropylene copolymer resin, featuring a gasket-sealed, water and dust tight, submersible design (MIL-STD 810H). Other standard features include a molded-in hinge, patented trigger release latch system, comfortable, snap-down rubber over-molded cushion grip handle, automatic ambient pressure equalization valve (MIL-STD 810H), and resistance to UV, solvents, corrosion, fungus and impact damage (MIL-STD 810H).

The 3i-2424M144U provides 4U of rack space with 20 in. rack depth for users who need additional mounting capacity in a durable iSeries Fly Rack case. Built for standard 19 in. rack gear, it combines a removable rack frame, watertight construction, in-line wheels, and a pull handle for easier mobility.
