Common questions
What does ECT-32 mean and why does it matter for my shipping needs?
ECT-32 (Edge Crush Test 32 pounds per inch) indicates the corrugated material can withstand 32 lbs of force per linear inch when crushed edgewise. This rating ensures reliable stacking performance in warehouses, protects contents during multi-layer pallet configurations, and meets standard carrier requirements for mid-weight products and vertical shipments.
Can these boxes replace mailing tubes for long items?
Yes. The 6 x 6 x 30" tall format provides protection compared to mailing tubes while offering easier access via end-loading design. The square footprint also stacks more efficiently on pallets and warehouse shelves than round tubes, reducing overall shipping costs and handling labor.
How many boxes fit on a standard pallet and what's the freight advantage?
Approximately 80 - 100 boxes per pallet depending on stacking height and configuration. The compact 6" square base maximizes pallet density, reducing freight-per-box costs on LTL and TL shipments while the flat-shipped bundle format cuts inbound receiving labor by up to 40% versus pre-assembled alternatives.
Is this a single-wall or double-wall box and what items can it safely ship?
This is single-wall corrugated rated ECT-32, ideal for lighter to mid-weight items under 30 lbs including fishing rods, shelving units, trophies, and retail merchandise. For heavier tall items exceeding 30 lbs, consider double-wall alternatives or consult our packaging specialists for custom solutions.
