Definition
A metal connector plate used to reinforce joints in pallet construction, particularly where stringers are spliced or where additional shear resistance is needed. Hitch plates are pressed or nailed into the wood at connection points, distributing stress across a larger area and preventing joint failure under load. They are commonly used in heavy-duty and custom pallet designs where standard nail connections alone are insufficient.

Splice
A joint where two pieces of lumber are connected end-to-end to create a longer component. In pallet construction, splices occur in stringers or runners when a single piece of lumber is not long enough to span the full pallet length. Spliced stringers are reinforced with metal plates, plywood gussets, or additional fasteners to maintain structural continuity. Splices represent potential weak points and must be properly engineered to maintain pallet load capacity.
Stringer
A continuous, longitudinal solid or notched board that connects and supports the deck boards of a pallet. Stringers are the structural backbone of stringer-style pallets, running the full length of the pallet and providing the framework that holds deck boards in place. Most standard 48x40 pallets use three stringers — two along the outer edges and one down the center.
Stiffener
A structural member added to a pallet to increase its rigidity and reduce deflection under load, particularly in racking applications. Stiffeners are typically boards or engineered wood elements placed between or beneath the deck boards, running perpendicular to the primary deck board direction. They distribute loads more evenly across the pallet span and are common in custom-designed pallets for heavy or concentrated loads.
Structural Grade
A lumber grading designation indicating that the wood meets specific strength and stiffness requirements for load-bearing applications. Structural-grade lumber is graded by certified inspectors using visual or machine stress rating (MSR) methods. In the pallet industry, structural-grade lumber is used for stringers, blocks, and lead boards in heavy-duty pallets where failure under load could cause safety hazards. Structural grading ensures predictable performance under engineering calculations.
