48 x 40 x 36 in gaylord boxes

This is the box people mean when they say "a gaylord" without a size. Its footprint is the pallet's footprint, so nothing hangs over, a stack of them lines up with the edge of the load below, and every forklift in the valley has driven under one. That is why single-trip empties from a distribution building are mostly this size, and why a buyer asking for a used gaylord almost always wants this one.

Along the Delaware it turns up in every trade. A Pureland food distributor receives it with dry ingredients. A resin compounder in Bristol Township ships regrind in it. A machine shop in Montgomery County fills it with fasteners and castings on a full-flap bottom. A packing shed in Cumberland County stages squash in it before the auction. Same box, four loads, four different answers on walls and bottom.

The 36 inch height is the sweet spot between a box that holds a useful load and one a worker can reach into. Taller boxes hold more but get awkward to unload by hand; shorter boxes are for dense goods.

For the 48 x 40 x 36 in box, the deck of a 48 x 40 pallet is 1,920 square inches. The footprint covers 1,920, or 100 percent of it. Weigh what you plan to put in, then see where you land against the 1,500 lb rating (triple wall, one maker).

Stay in the first three rows for a used box. A box below Grade A has already given up some of its rating.

Growers, plants and carriers each count in different units, so here is 48 x 40 x 36 in in the ones they use. A bushel is 1.2445 cubic feet, a cubic yard is 27, a US gallon is 0.1337 and a liter is 0.0353. Fill level matters: a box filled to 32 of its 36 inches holds 35.6 cubic feet, because the top four inches are for flaps and settling.

When you ask for this size, the three things we need are wall count, bottom and condition. Triple wall on a partial bottom suits resin or produce on a pallet. Triple or 4-wall on a full flap bottom suits parts. Double wall suits light packaged goods. Add your date and ZIP, and we answer by email with what we have.

Do not assume every 48 x 40 x 36 is rated the same. Wall count, board grade and bottom all move the rating, and a used box has lost some of it if it is below Grade A. The 1,500 lb figure above is one maker's triple-wall rating, not a promise for any box you receive.

Because the 48 x 40 x 36 matches the pallet, the stack arithmetic is simple. A trailer floor takes the boxes in whole numbers, the layers are set by the roof, and the weight is set by the rating. That is why quotes for this size come back fastest and why mixed used loads are mostly this size with a few exceptions.

If you are unsure what to ask for, ask for this one first and say what you plan to put in it. The reply will tell you if a short box, a tall one or an octagon would serve better.
