10 x 6 x 57" Telescoping Inner Boxes

This 10 x 6 x 57 inch inner carton is the sliding component of a two-piece telescoping box set. Built from ECT-32 kraft corrugated with a full overlap (FOL) bottom, it delivers reinforced base support while fitting inside the corresponding outer box to create a length-adjustable shipping solution without custom sizing.

The telescoping format is well suited for posters, curtain rods, fishing rods, architectural drawings, florals, and other tall or elongated items that exceed standard box proportions. It is commonly used in e-commerce fulfillment, manufacturing distribution, and retail supply chains where long-profile products must ship securely in consistent packaging.

Each inner box weighs approximately 1.52 lbs and is sold in bundles of 15. The matching outer box (T10657OUTER) is sold separately and is required to complete a functional set. Both components must be ordered independently to meet operational quantities.
