6 x 6 x 72" Telescoping Inner Boxes

This telescoping inner box is the inner component of a two-piece adjustable shipping system built for extended-length items. Constructed from ECT-32 kraft corrugated with a full overlap (FOL) bottom, it delivers reinforced base support suited to the demands of upright or standing loads. Interior dimensions measure 6 x 6 x 72 inches.

The telescoping format is well-matched to industries that regularly ship poles, tubes, rods, rolled artwork, framed prints, banners, or bundled pipe stock — any product where length varies or standard box depths fall short. The sliding two-piece design accommodates variable item lengths without cutting or custom tooling, making it practical for high-volume fulfillment and production-floor packing lines alike.

One inner box pairs with one outer carton (T6672OUTER) to complete a functional set. The inner box is sold in bundles of 15 and ships via parcel carrier.
