Two-Way vs Four-Way Pallets Fork Entry, Handling & What It Means for Your Warehouse
Florida Pallet Supply • Updated 2026-03-30
Fork entry - the number of sides a forklift or pallet jack can access a pallet from - is one of the most practical specifications you need to understand before ordering pallets. Specifying the wrong entry type for your equipment or racking layout creates handling bottlenecks, equipment damage, and safety risks.
This guide explains what two-way and four-way entry mean, how each construction is built, and how to choose based on your actual equipment and facility layout.

A two-way pallet can only be lifted from two opposite sides. The most common example is the standard stringer pallet, where three boards run the length of the pallet and the fork tines slide in from the short ends only. The closed sides block fork entry. Two-way pallets work perfectly well in most conventional warehouse environments where forklifts can always approach from the open ends. The limitation appears in tight aisles, rack-end configurations, or automated systems that require access from any direction.
Four-Way Entry Pallets
A four-way pallet allows fork entry from all four sides. True four-way entry uses block construction (nine blocks in a 3x3 grid) that creates open channels from every direction. Notched stringer pallets provide partial four-way entry by cutting rectangular notches into the solid stringers, allowing pallet jack wheels to enter but with reduced structural integrity at the notch. For full forklift four-way entry without structural compromise, block pallets are the correct choice.
Which Forklifts Require Four-Way Pallets?
Standard counterbalanced forklifts can work with two-way pallets in most configurations. However, reach trucks, turret trucks operating in very narrow aisles (VNA), automated guided vehicles (AGVs), and pallet conveyor systems all require true four-way entry pallets to function correctly. If your warehouse uses any of these systems, block pallets are not optional.
Practical Recommendation
For the majority of Florida warehouses, distribution centers, and manufacturing operations using standard forklifts and conventional racking, two-way (stringer) pallets are the right choice. They cost less, are easier to source, and are universally compatible with standard handling equipment. Upgrade to four-way block pallets only if your equipment or racking specifically requires it, or if you are operating in food processing or export environments where block construction provides additional benefits.
Frequently Asked Questions
Yes. Racking systems are designed to support pallets from the front; the number of fork-entry sides does not affect racking compatibility. What matters is pallet dimensions and load capacity.
No. Notched stringer pallets offer partial four-way entry (pallet jack only) but are still technically stringer construction. True four-way entry for all equipment requires block construction.
Not specifically because of fork entry - but export requirements (ISPM-15 heat treatment) are more commonly found on block pallets because block construction is the European standard. Your export compliance requirement is heat treatment certification, not necessarily four-way entry.

Two-way pallets allow forklift entry from two sides only (the short ends), while four-way pallets allow forklift entry from all four sides. Standard GMA stringer pallets are two-way entry unless their stringers are notched, which creates partial four-way access. Block pallets are full four-way entry by design. Four-way pallets are more efficient in facilities where forklifts approach from multiple directions, in tight racking configurations, and in operations using pallet jacks that require access from all sides.
