Opening Height – the vertical dimension measured between decks, from the floor to the underside of the top deck, or from the floor to the top of the stringer notch

Overall Height – the vertical dimension measured from the pallet bottom to the pallet top

Overhang – the distance the deck or deckboard extends from the outer face of the outer pallet stringer, stringerboard, or block; wing; lip; cantilever; distance the unit load extends beyond the deck


Pallet – a portable, horizontal, rigid, composite platform used as a base for assembling, storing, stacking, handling, and transporting goods as a unit load, often equipped with a superstructure

Pallet Design System (PDS) – a reliability-based computer-assisted design CAD program for wood pallets for determination of the safe load-carrying capacity, performance and economic life of wood pallets

Pallet Size – overall dimension of a pellet stated in terms of length followed by width and height; for example, a 48" x 40" pallet is 48" long and 40" wide; has 48" stringers or stringerboards and 40" deckboards

Partial Four-Way Stringer Pallet – a stringer pallet with notched stringers and block pallet with overlapping bottom stringerboard and deckboards


Racked Across Deckboards (RAD) – output of the PDS evaluation software describing the maximum load-carrying capacity and deflection of a wood pallet and its decks, where the warehouse racking frame supports the pallet only at the deckboard ends

Racked Across Stringers (RAS) – output of the PDS software evaluation describing the maximum load-carrying capacity and deflection of a wood pallet and its decks, where the warehouse racking frame supports the pallet only at the stringer or stringerboard ends

Repaired Pallet – pallet with damaged components replaced with new or recycled components, in order to reuse it

Recycled Pallet – a pallet that has been used, discarded, salvaged, repaired, or rebuilt in order to pass through another cycle or cycles of use … environmentally responsible

Stringer – continuous, longitudinal, solid or notched beam-component of the pallet used to support and space the deck components, often identified by location as the outside, interior, or center stringer; bearer; runner

Stringerboard – in block pallets, the continuous, solid board member extending for the full length of the pallet, perpendicular to the deckboard and placed between the deckboards and blocks, to serve as support of deckboards or deck


Top-Deck of Pallet – the assembly of components comprising the upper load-carrying pallet face

Two-Way Entry Pallet – a pallet with unnotched solid stringers allowing entry only form the two opposite pallet ends; a pallet without notches in stringers
