36 x 5 x 42" Side Loading Boxes

These 36 x 5 x 42-inch side-loading boxes are built from ECT-32 single-wall kraft corrugated with full overlap (FOL) flap construction. The FOL design closes each end with fully overlapping flaps, reinforcing the panels and distributing stacking loads more evenly than standard flap styles — reducing the risk of end-panel failure during transit and storage.

The side-loading configuration positions the opening at the end rather than the top, allowing horizontal insertion of flat, shallow, or panel-format goods. This makes them a practical choice for framed artwork, cabinet doors, shelving panels, foam inserts, mirrors, and similar products handled in retail distribution, furniture manufacturing, and millwork operations.

Each box is constructed from ECT-44 single-wall corrugated board and weighs approximately 4.4 lbs. Boxes ship and store flat to conserve shelf and floor space. Sold in bundles of 5.
