Fontaine Fifth Wheel Application When weight and cost are prime considerations, Fontaine's Angle Mount Fifth Wheel is the logical choice. Use it when your axle weight, bridge length and kingpin settings remain constant.
The Fontaine
Stationary Angle Mount Fifth Wheel (A36)![]()
The Angle Mount Fifth Wheel comes in a wide range of mounting heights, and incorporates the NO-SLACK® II standard and the 5092 heavy-duty top plates. Choose either top plate; both are built with low-alloy, high-tensile formed steel with a surface designed for uniform lubrication. Their heavy-duty steel substructure provides low weight, reinforced strategic load-bearing areas and high structural integrity.
Our patented locking system automatically eliminates any fifth wheel slack and includes an integral safety lock to prevent false coupling and premature trailer release. The one-piece cast saddle bearings are built with large grease grooves to ensure uniform grease flow and coverage.
Safety and convenience are engineered into our Angle Mount Fifth Wheel.
So, when the choice is a stationary fifth wheel, choose the leader -- the Fontaine® Angle Mount Fifth Wheel.
