Use this guide to determine which box is right for you.
Cheaper boxes may not survive the hazards of shipping and handling. Uline refuses to sacrifice the quality of our boxes. Uline's 200 lb. test boxes help protect your products.
200 lb. Test
Uline 200 lb. test boxes ensure greater bursting strength than 32 ECT boxes. Greater bursting strength means fewer crushed and damaged boxes during shipping.
The first dimension is length. Length is always the longest side of the box that has a flap.
The next dimension is width. The width side also has a flap, but is always the side shorter than the length.
Height is the only dimension without a flap. The height measurement does not include flaps.
NOTE: Acceptable manufacturing variance is +/- 1/8".

200 lb. test refers to bursting strength, while 32 ECT refers to stacking strength. Boxes that meet 200 lb. test will also exceed 32 ECT stacking strength.
