18 x 7 x 52" Side Loading Boxes

This 18 x 7 x 52 inch side-loading corrugated box is built with full overlap (FOL) bottom construction on ECT-44 single-wall board, delivering reinforced base strength that standard RSC boxes at this size cannot match. The FOL design distributes load weight across the entire bottom panel, making it a dependable choice for heavy or dense contents that concentrate stress at the base during transit.

The side-loading configuration lets packers insert long, rigid items horizontally — a practical necessity for items like curtain rods, athletic equipment, framing materials, rolled textiles, or industrial components that cannot be dropped in from above. These boxes are well-suited for e-commerce fulfillment, retail distribution, and manufacturing environments where elongated goods require a purpose-built solution rather than an oversized general-purpose carton.

Constructed from ECT-44 corrugated board, each box weighs approximately 3.064 lbs and ships flat to keep warehouse footprint minimal until pack time. Bundles of 5 are parcel-friendly, allowing convenient replenishment without lead-time delays.
