Fifth Wheel S/A Plate
SAF-Holland

This self-aligning, plate-style component is positioned within the fifth-wheel pocket as a crucial interface for precise, repeatable coupling in heavy-duty trucks. The self-aligning (S/A) design promotes easier hitch engagement by accommodating minor misalignments between tractor and trailer, reducing coupling effort and enhancing first-pass engagement reliability. As part of the fifth-wheel plate family, it shares common mounting patterns and compatible hardware with other S/A variants, enabling flexible fleet configurations without costly rework. The lack of explicit dimensional data is offset by the established compatibility within category 42763, which covers standard fifth-wheel assemblies. VMRS code 059-001-001 identifies it as a primary top-plate element, and the absence of cross-references indicates straightforward substitution among compatible plates in the same platform family. This plate is particularly beneficial in high-cycling applications where rapid, repeatable hookups are necessary, such as fleet-intensive regional distribution or long-haul operations with frequent disconnect/reconnect cycles.
