What the classification says
The stacking frame or the corner posts are deformed.
How to spot it
Sight down each corner post and check the top frame sits square so the next box locates on it.
Effect on the pallet's class
Not exchangeable. See Not fit for use for the full criteria.
Repair
Licensed repair only.
If no licensed repairer is practical, sell sound timber as non-EPAL wood or send the pallets for recycling.
