The Pelican-Hardigg™ ISP Case IS4525-2103FT is a rotomolded InterStacking Pattern transit case with interior dimensions of 44.75" x 24.75" x 24.25", exterior dimensions of 47.75" x 27.75" x 29.63", and an empty (no-foam) weight of 69.9 lbs. base and lid depths are 21.31" / 2.94".
The IS4525-2103FT uses Pelican-Hardigg™'s patented Inter-Stacking Pattern (ISP): a disc pattern on the base drops into the wave pattern of the case below, so cases lock together and virtually eliminate load shift. Cross-stacking builds tight, stable loads and can cut time spent strapping and netting.
The ISP line spans six sizes from roughly 4 to 25 cubic feet and is sized to make the most of standard pallets, NATO pallets, JMIC containers, 463L pallets, and sea containers. A silicone sponge O-ring and pressure-release valves keep it sealed against extreme weather and wet conditions.
TacRugged customizes the IS4525-2103FT with hardware, protective coatings, integration panels, and custom foam interiors so it secures your gear the way it actually ships and stacks.
