The side picture is of a Block design pallet. Block or Post pallets can be partial or full four-way entry. The typical block pallets can have 4-12 blocks as support for the top deck boards or mat. The length of the stringer board determines a Block pallets length, which is located between the top deck and the top of the blocks. The length perpendicular to the stringer length determines the width. Block pallets can have a variety of bottom deck configurations. There may be no bottom boards, boards parallel to the deck boards or a full parameter base similar to a picture frame.

• 44" x 56" Block Pallets
