Cut Up to 40% Shipping Costs via Nested Packaging

Because wiring ducts are hollow profiles, shipping unfilled volume by sea container is extremely costly. iTUNG's precision calibrated inner/outer wall tolerances allow small duct profiles to be systematically nested inside larger trunking.

Extra Payload per 40HQ

Example nesting scheme: IT-2525 nested into IT-6080, or IT-1616 into IT-4060. Barcoded neutral packaging with clear separation labels prevents job-site mix-ups.
