Building your loads within the pallet footprint is one of the key elements to avoiding damage.  Any time cargo hangs over the edge of the pallet, the weight from above coupled with lack of support can quickly compromise the integrity of the product.   In addition, any portion of the load protruding past the pallet can easily catch on adjacent objects.  Placing your freight in a tote is preferred but barring this we strongly suggest building your loads within the pallet footprint.
