10 1/2 x 10 1/2 x 48" Telescoping Outer Boxes

This 10 1/2 x 10 1/2 x 48 inch telescoping outer box is the outer component of a two-piece adjustable corrugated set. It slides over a matching inner box to create a variable-length shipping carton, allowing the assembled length to be sized to actual contents rather than a fixed dimension. The full overlap (FOL) bottom construction distributes stacking loads across the entire base panel, reinforcing the structure where tall, narrow cartons are most vulnerable.

The tall, narrow profile makes this configuration well-suited for long or extended items such as curtain rods, dowels, fluorescent tubes, poster tubes, sporting goods, and industrial components. It is a practical choice for manufacturers, distributors, and fulfillment operations shipping slender goods that standard fixed-depth boxes cannot accommodate efficiently. Adjusting the overlap reduces void fill and can lower dimensional weight in transit.

Constructed from ECT-32 single wall kraft corrugated. This listing is for the outer box only — one inner carton and one outer carton are required to complete a usable set; the inner box (T101048INNER) is sold separately. Sold in bundles of 20.
