Slide Base and Bracket
SAF-Holland

Slide base and bracket assemblies form a critical support system for adjustable mounting configurations in heavy vehicle applications. This two-piece arrangement acts as a movable foundation that accommodates alignment changes between the chassis and the fifth wheel or related mounting structures. The VMRS code 059-001-003 places it within the framework of ride and trailer coupling hardware, while the category context (42807) identifies its role in mounting hardware and base components. The design emphasizes stiffness and resistance to shear under dynamic loads, ensuring consistent contact and alignment when the slider base is positioned for correct tongue alignment. In service, technicians benefit from straightforward installation, predictable wear patterns, and simplified inspection routines. The component is particularly valuable in fleets that require frequent rotation of fifth wheel height or position to optimize payload balance or to accommodate different trailers. As with all related safety information, consult Prop 65 documentation and handle with standard PPE during installation and maintenance.
