Definition
A pallet design that allows forklift forks or pallet jack forks to enter from all four sides. True four-way entry is achieved through block pallet construction, where blocks replace continuous stringers, creating openings on all four sides. Some stringer pallets offer partial four-way entry through notched stringers, which allow fork entry on the stringer sides. Four-way entry pallets are preferred for tight warehouse spaces and automated handling systems.

Two-Way Entry
A pallet design that allows forklift or pallet jack forks to enter from only two opposite sides, typically the sides perpendicular to the stringers. Two-way entry is characteristic of stringer pallets without notched stringers. While less versatile than four-way entry pallets, two-way entry designs are simpler and less expensive to manufacture and can be sufficient for applications where pallets are always oriented the same way.
Block Pallet
A pallet constructed using blocks of solid wood or composite material between the top and bottom deck boards, typically with nine blocks arranged in a 3x3 pattern. Block pallets offer true four-way entry, allowing forklifts and pallet jacks to access the pallet from all four sides. They are generally stronger and more durable than stringer pallets, making them common in pooling programs and heavy-duty applications.
Notched Stringer
A pallet stringer that has been cut with notches (typically two per side) to allow partial forklift fork entry from the stringer side of the pallet. Notched stringers convert a two-way entry stringer pallet into a partial four-way entry pallet, increasing handling flexibility. The notches reduce the stringer's structural capacity somewhat, so notched stringer pallets typically have lower load ratings than full stringer pallets of the same dimensions.
Pallet
A flat transport structure, typically made of wood, that supports goods in a stable fashion while being lifted by a forklift, pallet jack, or other jacking device. Pallets are the foundation of modern material handling and logistics, enabling efficient storage, stacking, and transportation of goods. The most common pallet size in North America is the 48x40 inch GMA pallet.
