Built for palletized logistics, the Pelican-Hardigg™ ISP Case IS4537-2303 measures 45" x 37" x 26" inside and 48" x 40" x 32" outside, with an empty weight of 93 lbs. With foam it weighs 148 lbs, base and lid depths are 23" / 3".
The IS4537-2303 is part of Pelican-Hardigg™'s ISP system, where the base's disc pattern interlocks with the wave pattern of the case below to lock cases together. The result is tight, self-aligning stacks that reduce load movement and the strapping needed to secure them.
Across six sizes from roughly 4 to 25 cubic feet, the ISP system is built to fill standard pallets, NATO pallets, JMIC containers, 463L pallets, and sea containers efficiently, and its silicone sponge O-ring and pressure-release valves keep contents protected in harsh, wet environments.
The IS4537-2303 carries MIL-STD-810F testing. TacRugged adds hardware, protective coatings, integration panels, and custom-cut foam so the case fits your equipment and handling.
