Two-Way vs Four-Way Pallets
Fork Entry, Handling & What It Means for Your Warehouse

Florida Pallet Supply • Updated 2026-07-28

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.

Pallet Lumber & Sawmill Operations

Stamped kiln-dried pallet lumber, bulk warehouse stock, dimensional yard inventory, raw softwood logs, and sawmill operations - the supply chain behind every custom and standard pallet we ship.

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.

Two-Way vs Partial Four-Way vs True Four-Way: Entry and Equipment (as of July 2026)

The three constructions people mean when they say two-way or four-way, and what each one actually lets your equipment do. The distinction that costs operations the most money is the middle row: a notched stringer pallet is sold as four-way, but only a pallet jack can use the notched side. Your forklift still enters from the ends.

ConstructionFork entry sidesCounterbalanced forkliftPallet jackReach, turret, VNA, AGV, conveyorStructural note
Two-way stringer (solid stringers)2, short ends onlyYes, from the endsNo, long sides are closedNot suitableFull stringer strength; no notch to weaken
Partial four-way stringer (notched)2 for forklifts, 4 for pallet jacksFrom the ends onlyYes, wheels enter the notchesNot suitableReduced integrity at the notch
True four-way block (nine blocks, 3x3)4, all sidesYes, from all fourYes, from all fourRequired; these systems will not run without itNo notch weak point; the European standard

Delivered 48x40 stringer pricing in truckload quantity runs $5 to $9 for Grade B recycled, $9 to $13 for Grade A recycled, and $14 to $18 new, as published on our pallet cost guide. Notching adds a small premium over a plain stringer. Block pallets sit above the stringer tiers and are quoted per order because block count, wood spec, and treatment vary. Verified July 2026.

Which Entry Type Your Equipment Actually Requires (as of July 2026)

Work down this table against the equipment list for the facility that will receive the load. If any single line requires true four-way, the whole lane needs block pallets, because a mixed fleet is what creates the jams.

Your equipment or layoutMinimum entry typeWhyWhat goes wrong if you get it wrong
Standard counterbalanced forklift, conventional rackingTwo-way stringerForks always approach from an open endNothing; paying for block here is wasted spend
Manual or electric pallet jack on the long sidePartial four-way (notched)Jack wheels need the notch to enterOperators drag or re-orient loads by hand, slowing every pick
Reach truckTrue four-way blockApproach angle is constrained in the aisleMissed engagements and damaged stringers
Turret truck in very narrow aisle (VNA)True four-way blockThe truck cannot reposition to find an open endLoad cannot be picked at all in the aisle
Automated guided vehicle (AGV)True four-way blockAutomation has no operator to re-orient the palletHard stops and fault states on the line
Pallet conveyor or ASRSTrue four-way blockTransfer points engage from more than one axisJams, and notched stringers can snag and shear
Export shipment under ISPM-15Either; treatment is the real requirementCompliance is heat treatment, not fork entryRejected at the border for treatment, not for entry type

Export note: block construction shows up on export loads more often because it is the European standard, not because customs requires four-way entry. The compliance requirement is the ISPM-15 heat-treatment stamp. See our heat-treated and ISPM-15 guide. Verified July 2026.

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.

Ready to Order Pallets for Your Operation?

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.
