Rack fit
checker.

Pallet overhang on a beam is the leading cause of catastrophic rack failure, and it is almost always a dimension mistake made before anybody measured the bay. Four measurements and a load weight is all this needs.

Footprint tested: 48" × 40" GMA
Positions per bay: 2
Required capacity: 3,200 lb
Recommended grade: None — redesign

Send us the bay and the load

Put the four measurements in the message field and we will specify the footprint, the grade and the repair standard that keeps it safe.

No phone tag. No sales sequence. One reply from one person.

Verdict

48" × 40" GMA fits, but no grade we sell is safe at 3,200 lb.

Fit wire mesh decking, reduce the pallet load, or move to a purpose-engineered pallet. Do not run this position on a recycled deck.

Orientation options

Orientation	Per bay	Depth needed	Verdict
40.0" face out	2	48.0"	Overhangs
48.0" face out	2	40.0"	Fits the depth

Height arithmetic

Step	Value
Clear height to the beam above	60"
Less pallet height	−5.5"
Less clearance for entry and settlement	−4"
Usable load height	51"

Capacity against every grade

Required capacity is your load weight times a safety factor of 2.0 — 1.5 for handling, 2.0 once a load sits for three months or more. With deck support the static rating applies instead of the racked one.
Grade	Racked	Static	Meets 3,200 lb?
#2 recycled	Not advised	3,200 lb	No
#1 recycled	1,500 lb	4,000 lb	No
A / Premium	1,800 lb	4,600 lb	No
New hardwood	2,200 lb	5,000 lb	No
EPAL block pallet	2,200 lb	8,800 lb	No

Rules this tool applies

No part of the pallet may project beyond the bay depth
Load may overhang the deck by no more than one inch per side
Racked capacity is roughly a third of static capacity
Wood creeps: three months or more means a 2.0 factor
Wire decking converts the position to a static one
Plugged #2 decks are never racked unsupported

Other clearances worth checking

Flue space, back to back: ≥ 6"
Beam span for two 48×40: ≥ 96" clear
Minimum fork entry height: 3½"
Loaded 48×40 through a door: ≥ 50" clear
Sprinkler clearance to load: Per your fire code
Upright damage tolerance: Inspect quarterly

Grades, side by side

Load figures are observed operating capacities for a 48×40 footprint under a uniformly distributed load. Apply your own safety factor — 1.5 for dynamic handling, 2.0 for long-term racked storage. Price index: 100 = new hardwood.

Handling and rack dimensions

Measure your own equipment before specifying a pallet. These are the values that decide whether a footprint works in your building.
Dimension	Typical value	Note
Fork length	42"–48"	Must not protrude beyond the far side of a 48" pallet
Fork width	4"–6"	Wider forks spread load across deck boards
Fork thickness	1½"–2"	Determines minimum pallet entry height
Fork spread, GMA entry	24"–27" centres	Between the stringers of a three-stringer pallet
Pallet-jack wheel path	6½" clear	Why notched stringers do not admit jacks
Minimum entry height	3½"	A crushed bottom deck blocks the forks entirely
Rack beam span, two pallets	≥ 96" clear	For two 48×40 pallets, 40" face out
Flue space, back to back	≥ 6"	Most fire codes; check your jurisdiction

The life of one deck, stage by stage

Durations are medians from our line records and the Passport programme; the population is survivor-biased and we say so.
Stage	Typical duration	What happens	Carbon position
Timber to pallet	Weeks	Sawn, nailed, often shipped wet	12.6 kg CO₂e embodied
First life	2–4 years	Hardest service; lead board usually fails	Credit begins at reuse
First repair	2 minutes	Lead board replaced with salvaged stock	+1.8 further lives on average
Second to fifth life	6–12 years	Grading, companions, re-nailing, re-grading	11.6 kg CO₂e avoided per cycle
Structural retirement	—	Stringers rotted or deck beyond rebuild	Stored carbon still retained
Repurposed	Decades	Collars, crates, table tops, cladding	Carbon stays in the material
Fiber	1–3 years	Mulch or bedding, then soil	Released slowly
Thermal	Immediate	Boiler-grade chip	Released at once — last resort

Glossary — thirty terms worth knowing

Core: A used pallet bought for grading — the currency of the industry.
Deck board: Any board on the top or bottom face of a pallet.
Lead board: The outermost deck board at each end; absorbs every fork entry.
Stringer: The long member running the length of a stringer pallet; usually three.
Stringer board: On a block pallet, the board that ties the blocks together.
Block: One of the nine supports in a block pallet.
Notch: The cut-out in a stringer that creates four-way fork access.
Chamfer: A bevel on a lead board's lower edge to ease fork entry.
Companion: A full-length board nailed alongside a damaged stringer. A strong repair.
Plug / scab: A short piece fixed over a break. A weaker repair; #2 grade here.
Re-nail: Restoring the fastener pattern on a loose but intact pallet.
Regrade: Moving a pallet between grade lanes after inspection.
Down-cut: Re-cutting a larger deck into a smaller footprint.
Static load: Capacity at rest on a flat, continuous surface.
Dynamic load: Capacity while being lifted and moved.
Racked load: Capacity spanning beams with no deck support. Always the smallest figure.
Unit load: Pallet, product and wrap considered as one structure.
Overhang: Load or deck projecting beyond its support. The leading cause of rack failure.
Flue space: The gap between back-to-back rack bays; six inches minimum in most codes.
GMA: The Grocery Manufacturers Association 48×40 specification.
EPAL: The licensing body for the European 1200×800 block pallet.
ISPM-15: The international phytosanitary standard for wood packaging.
HT: Heat treatment: 56 °C at core for 30 minutes.
IPPC mark: The wheat-sheaf stamp evidencing phytosanitary treatment.
Collar: Four hinged timber sides that turn a pallet into a container.
Top cap: A lightweight cover protecting the uppermost layer of a stack.
Dunnage: Timber used to fill voids, brace loads and spread point loads.
Fiber: Ground wood: mulch, animal bedding or boiler-grade chip.
Diversion rate: Share of intake kept out of landfill. Ours is 100%.
Reuse rate: Share of intake that leaves as a pallet. Ours is 94%.
