Common questions
Why do I need both inner and outer boxes for this telescoping system?
The two-piece telescoping design allows the outer box to slide over the inner box, creating adjustable height capacity. The inner box provides the base structure while the outer box extends the walls upward, enabling you to accommodate items ranging from 6" to 38" tall without maintaining multiple box SKUs.
What does ECT-44 mean, and how does it affect my shipping costs?
ECT (Edge Crush Test) 44 rating means each linear inch of the box edge can withstand 44 pounds of crushing force, meeting TAPPI standards for heavy-duty applications. This burst strength reduces damage claims, minimizes freight surcharges for fragile goods, and allows secure stacking 3-4 high on pallets, maximizing truck capacity and ROI.
How does the FOL (full overlap) bottom improve performance compared to standard bottoms?
Full overlap bottoms extend the side flaps completely across the base, creating a double-wall foundation that resists puncture, supports heavier loads, and prevents crushing when stacked. This design is essential for LTL freight and high-velocity warehouse operations where boxes may experience compression from forks or pallet jacks.
What irregular shapes and heights can these boxes accommodate?
The adjustable 48" x 6" footprint and 6" to 38" variable height accommodate tall rolls, tubes, lightweight machinery, bundled textiles, posters, prints, and columnar products. The fixed 48" length and 6" width work for items requiring consistent length/width but varying height, eliminating custom box expenses while reducing inventory complexity.
