Four-way pallet: partial vs true 4-way entry explained

Summary

A four-way pallet can be entered from all four sides. A partial 4-way pallet is a stringer pallet with notched stringers: forklifts enter all four sides, but pallet jacks only the two ends. A true (full) 4-way pallet is usually a block pallet, which forklifts and pallet jacks can enter from every side.

"Four-way" is one of the most common words on a pallet RFQ and one of the most misunderstood. There are two kinds, and they behave differently with pallet jacks. Say which one you mean.

What is a four-way pallet?

A four-way pallet has fork openings on all four sides. The Uniform Standard for Wood Pallets separates two entry classes:

Entry class Forklift Pallet jack Typical construction
Partial 4-way All 4 sides 2 ends only Stringer pallet with notched stringers
Full (true) 4-way All 4 sides All 4 sides Block pallet

A pallet jack's forks carry load wheels that drop to the floor inside the pallet. On a notched stringer pallet, the bottom deckboards run across the notches' path, so the wheels have nowhere to go from the side. On a block pallet, the bottom deck leaves openings on every side.

How is a partial 4-way pallet built?

The stringers of a stringer pallet get two notches each. Typical values on a 48 × 40 in:

Notch feature Typical Metric
Length 9 in 229 mm
Depth 1 to 1-1/2 in (1-1/4 in common) 25–38 mm (32 mm)
Start from stringer end 6 in 152 mm
Corner radius 1/2 to 1-1/2 in 13–38 mm
Opening height (notch + bottom board) about 2 in recommended about 51 mm

The Uniform Standard does not accept square notches and recommends at least 7 in (178 mm) of flat top between the notches. The bottom deckboards are placed to clear the notch zones. The GMA pallet is the standard example.

How is a true 4-way pallet built?

A block pallet has nine blocks with openings between them on every side. The pallet.design 48 × 40 block template has 3-1/2 in (89 mm) tall blocks under 3/4 in (19 mm) stringerboards and a perimeter bottom deck of 5/8 in (16 mm) boards. EUR/EPAL pallets have 78 mm (3.1 in) blocks. Bottom boards are often chamfered so jack wheels can roll over them.

Some plastic pallets are also true 4-way: designs with nine feet or a perimeter base.

Where are four-way pallets used?

  • Partial 4-way: most US grocery and retail freight on GMA pallets, cross-docking, trailers loaded from the side.
  • True 4-way: pooled pallets, European logistics, automated warehouses, retail back rooms where pallet jacks must enter any side.

Pros and limits

Partial 4-way True 4-way
Handling flexibility Good for forklifts, limited for jacks Full
Cost Low (stringer pallet + notching) Higher
Racking across length Notches reduce stringer section Depends on stringerboards and blocks
Repair Easy Easy (blocks and boards replaceable)
Typical weight, 48 × 40 30–70 lb (14–32 kg) about 45–70 lb (20–32 kg), estimate

Capacity

Notches remove wood from the stringer at points of high stress, so a notched stringer is weaker when the pallet is racked across its length than an unnotched one of the same size. Designers compensate with deeper or wider stringers. Block pallet capacity depends on block, stringerboard and bottom deck sizes. For either type, the manufacturer's rating for your support condition is authoritative. See pallet load capacity.

ISPM 15

Wooden four-way pallets need heat treatment and an ISPM 15 mark for most export.

What drives the cost?

  • Partial 4-way: notching adds a small machining cost to a stringer pallet
  • True 4-way: block construction adds components (9 blocks, 3 stringerboards) and labour
  • Lumber volume, species, heat treatment, volume and freight

Specifying a four-way pallet for a quote

  • Say "partial 4-way (notched stringer)" or "full 4-way (block)"; "4-way" alone is ambiguous
  • Whether pallet jacks must enter from the sides
  • Notch length, depth and position, or block and bottom-deck layout
  • Minimum opening size for your equipment (tine width, jack height)
  • Footprint, deck boards, species, fasteners
  • Load, racking and stacking
  • ISPM 15 HT
  • Quantity and delivery location

Frequently asked questions

What is a partial 4-way pallet?

A stringer pallet with notches cut in the stringers. Forklift tines can enter through the notches from the sides, but a pallet jack cannot, because its wheels would hit the bottom deckboards.

Is a GMA pallet 4-way?

It is partial 4-way. The three stringers are notched, so forklifts can enter from all sides but pallet jacks only from the ends.

What makes a pallet true 4-way?

Openings on all four sides that are wide and tall enough for pallet-jack forks and have open floor space for the wheels. Block pallets with perimeter or unidirectional bottoms achieve this.

Do 4-way pallets cost more?

Partial 4-way adds only a notching step to a stringer pallet. True 4-way block pallets cost noticeably more because they have more components and a two-stage assembly.
