Pallet types and how forks get in

Pallet types are two questions asked of the frame: how it is built, stringer or block, and where the forks can enter, two ways or four.

Frame and entry are different questions

stringer: forks in two endsblock: forks in from any side
Not to scale. A block pallet rests on blocks, so forks enter any of four sides; a stringer pallet is open on two ends unless the stringers are notched.
Four words, two questions
WordQuestion it answersWhat it means
StringerHow is the frame built?Three or more parallel timbers carry the deck
BlockHow is the frame built?Parallel and perpendicular stringers; entry from any side
Two-wayWhere can forks go?Forks enter from two opposite sides
Four-wayWhere can forks go?Forks enter from all four sides; usually heavier and tougher

A stringer pallet is two-way unless its stringers are notched, in which case it can be lifted from all four sides. A block pallet is four-way by design. The words overlap, which is why an order should give both answers.

What the dock decides

  • Pallet jacks and forklifts both work on two-way stock if you approach from the right sides.
  • Cross-docks that turn loads in tight spaces prefer four-way.
  • Racking and conveyors may need a particular build.
  • Some buyers will not take notched stringers on a heavy load.

Ask your own dock which entries its equipment needs, and name them in the request along with the size and grade.

Asking for a build in plain words

You rarely need the full vocabulary. Describe how forks will reach the pallet and the weight of the load, and the build can be proposed. "Forks from all four sides, 2,000 pounds, drums" points to a block pallet. "Forks from the ends only, light cartons" points to a plain stringer pallet.

Four-way

A four-way pallet takes forks from all four sides. It is usually heavier, bigger and more durable than a two-way pallet, and it can be lifted from whichever side is nearest, which saves seconds on every lift in a busy fulfillment aisle.

Of the two ways to get four-way entry, the block build is stronger. A notched stringer pallet is cheaper and lighter, takes a lighter load from the sides than from the ends, and has less wood where the cut is, so it is more likely to crack there.

What to check

  • Whether the entry gaps are wide enough for your forks.
  • Whether notches have cracked stringers.
  • Whether the pallet is block or notched.
  • Whether the weight suits your load.

When selling, count four-way stock apart from two-way. It is the version most docks ask for first, and a stack described as four-way is easier to place. See selling used pallets and 48 x 40 pallets.
