The BSC PREFERRED HD121218DW is a heavy-duty, double-wall corrugated shipping carton built from 275DW/ECT-48 kraft corrugated material. This construction delivers roughly twice the stacking strength and puncture resistance of a standard single-wall carton, making it suitable for dense, heavy, or high-value trade supply shipments. The cartons ship flat, reducing storage footprint on the job site or in the warehouse. Each pack contains 15 cartons. This SKU is also equivalent to part number S-16516. It is sized at 12 x 12 x 18 inches, fitting a wide range of mid-size components and parts.
These cartons are appropriate for shipping, storing, and staging trade supply materials including HVAC components, plumbing fittings, electrical parts, and pool equipment. The double-wall construction is particularly useful when stacking multiple cartons or shipping products that require extra crush resistance during freight transit. Sold in bundle quantities, they are well suited for supply houses, distributors, and contractors who need reliable bulk packaging stock on hand.
Designed as a general-purpose heavy-duty shipping and storage carton suitable for packaging trade supply products across HVAC, plumbing, electrical, and pool service applications.
No tools or code compliance is required for carton assembly. Store flat in a dry location away from moisture to maintain corrugated integrity. Avoid stacking beyond the rated ECT-48 compressive strength limit when cartons are loaded. Handle with care during transit to preserve double-wall construction performance.
