Fontaine’s fifth wheel bracket

Fontaine Fifth Wheel PML MountFontaine Fifth Wheel’s Adjustable Plate Mount fifth wheel bracket replaces the company’s PMA and APB models with a single lightweight model that features a reinforced cast steel design built to provide the same load capacity. The mount is composed of fixed brackets that sit on a steel plate base; each side of the base has six mounting holes designed to allow the fifth wheel assembly to be moved forward or backward in two-inch increments to help balance any load.

Since there is no sliding mechanism, the fifth wheel assembly is lighter, and there are less moving parts to maintain; to further minimize maintenance needs, the PML mount’s brackets feature greaseless liners to prevent metal-on-metal contact and dual durometer bushings to aid in shock absorption.

The PML mount is compatible with Fontaine’s No-Slack II 6000, 7000 and 7000CC top plates for standard- to moderate-duty on-highway use. When paired with a 6000 top plate, the PML assembly has a 50,000-pound vertical load capacity; when equipped with a 7000 or 7000CC top plate, it can handle a vertical load of up to 55,000 pounds.
