Pelican's Pelican-Hardigg Inter Stacking Pattern (ISP) cases are designed to stay secure in transit with patent-pending "wave design" stacking ribs on their lids and molded in-discs on their bottoms that work to lock the cases together in a stack.

The integrated wave design also allows for cross-stacking across all six ISP case sizes and enhances their rotationally molded polymer construction's load-bearing properties.

The ISP cases fit most known pallet sizes and feature an "O" ring seal to ensure that the case stays secure and watertight in transit, an internal atmospheric purge valve, and up to eight "comfort grip" high-impact polymer handles for team lifting.

All models come standard with lockable steel cable catches with a cobalt finish, and an integrated card label holder. For one-person transit, edge casters are included on select models, and skid runners are included on larger models.

ISP cases are available in six sizes that can accommodate a range of up to 25 cubic feet of usable storage space. The cases are also available in black, grey, desert tan, OD green and Safety Red, along with a variety of optional features that include stainless steel hardware and a choice of purchasing the case with or without layers of polyethylene foam.
