This 14 x 14 x 14 inch double wall corrugated box carries an ECT-71 edge crush test rating, placing it in the heavy-duty tier of corrugated packaging. Two fluted mediums bonded between three liner sheets deliver stacking strength and puncture resistance that standard single wall boxes cannot match — making it a reliable choice wherever compression performance and transit durability are non-negotiable.

The cubic interior format suits dense, irregularly shaped, or high-value products that require extra structural protection. Common applications include industrial parts distribution, automotive components, heavy consumer goods, and manufacturing outbound shipments where load weight or stacking height would stress lighter-rated boxes.

Constructed to ECT-71 double wall spec, each box weighs approximately 2.411 lbs and ships flat for efficient storage. Sold in bundles of 15 and parcel-friendly.
