Common questions
Do I need to buy the outer box separately?
Yes. The T8848INNERDW is the inner component only. You must purchase the T8848OUTERDW outer box to complete a functioning telescoping set. Both are required to form one adjustable carton.
What is ECT-48 and why does it matter for my warehouse?
ECT (Edge Crush Test) 48 means this corrugated can withstand 48 pounds of force per linear inch. Double wall construction (two fluted layers) provides stacking strength and impact resistance, reducing damage claims and product loss in high-volume fulfillment operations.
How does the FOL bottom improve box performance?
Full Overlap (FOL) bottom design means the bottom flaps fully overlap when sealed, eliminating weak points and distributing weight more evenly. This increases load-bearing capacity and reduces risk of puncture or collapse during multi-tier stacking and transport.
Can I use these boxes for different product heights?
Yes, that's the advantage of the telescoping design. The inner and outer box create an adjustable system that can be compressed or extended to fit items ranging from shorter to the full 48" height, eliminating the need to stock multiple box sizes and reducing packaging waste.
