12 1/2 x 12 1/2 x 72" Telescoping Outer Boxes

The 12 1/2 x 12 1/2 x 72 inch telescoping outer box is the cap component of a two-piece adjustable corrugated shipping system. Manufactured from ECT-32 kraft corrugated board with a full overlap (FOL) bottom, this outer carton slides over a corresponding inner box to form a single unit with adjustable finished height.

The telescoping design is well suited for tall or elongated items that standard fixed-depth boxes cannot accommodate efficiently — including framed artwork, lighting fixtures, architectural molding, sporting equipment, and industrial components. Adjusting the overlap to match actual item length reduces void fill and helps control dimensional weight in transit.

The FOL bottom distributes load stress across the full base panel, adding structural support for heavier contents. Each outer box weighs approximately 3.155 lbs. Bundles contain 15 outer boxes. The matching inner box (T121272INNER) is sold separately and must be ordered to complete each telescoping set.
