Common questions
Do I need both the inner and outer boxes?
Yes. The T4448OUTER (this product) is the outer sleeve. You must also purchase the T4448INNER box to create a complete telescoping set. Both components are sold separately to allow flexible ordering and cost control.
What is ECT-32 and why does it matter?
ECT (Edge Crush Test) 32 means the box withstands 32 pounds of crush force per linear inch. This single-wall grade is ideal for moderate-weight items and stacking scenarios common in fulfillment centers, balancing durability with cost efficiency.
How does the FOL bottom improve box performance?
Full Overlap (FOL) bottom design doubles the material overlap at the box base, significantly increasing compression strength and preventing bottom failure during stacking or rough handling. Critical for tall boxes storing heavier items.
Will this reduce my freight costs on tall shipments?
Yes. The adjustable telescoping design lets you ship products at their actual height rather than a fixed dimension, reducing DIM weight charges. Combined with the lightweight ECT-32 kraft construction, you see immediate savings on parcel and LTL shipping.
