Pallets customized with form-fitted mounts can provide maximum support for large fragile specimens, preventing them from being abraded on shelving, or being bumped into one another. Access to even the heaviest specimens is relatively easy and safe using a forklift, no matter how high the shelf is. In addition, storage can be organized following a logical sequence rather than simply keeping the heaviest specimens close to the floor. However, for safety in earthquake-prone areas, the heaviest specimens should be kept as low to the floor as possible. Relatively inexpensive pallet rack storage systems can be designed to take advantage of all the available height of a room, thus maximizing the use of space.
