Common questions
How much assembly time does each tube require?
Less than 10 seconds per tube. Simply fold along pre-scored lines and insert locking tabs, no tape, glue, or tools needed.
What makes triangle tubes better than round tubes for shipping?
Triangle design opens lengthwise for easier content insertion and removal, ships flat for 40% space savings compared to pre-assembled round tubes, and offers stacking stability during warehouse storage and transit.
Are these tubes compliant with major shipping carriers?
Yes. ECT-32-B corrugated construction meets USPS, UPS, and FedEx specifications for protective mailing, with burst strength suitable for documents, artwork, and moderate-weight contents.
What's the crush resistance rating?
ECT-32-B provides 32 ECT (Edge Crush Test) rating, delivering approximately 200 lbs per linear inch crush strength, ideal for protecting rolled documents and preventing damage from stacking.
