The Fontaine
Fifth Wheel Stationary Long Plate Mount (PLA)![]()
Strategic load-bearing areas are reinforced. The corrugated mounting plates are available in long or short lengths with mounting brackets in a variety of heights to fit your hauling needs.
Our unique Plate Mount is as safe and convenient as it is strong. The patented NO-SLACK® II locking system automatically eliminates fifth wheel slack, and the design includes an integral secondary safety lock to prevent false coupling and premature trailer release.
The Plate Mount is available with Fontaine's NO-SLACK® II standard or 5092 heavy-duty top plates incorporating low-alloy, high tensile formed steel and a heavy-duty steel substructure for high structural integrity. The surface of our top plates is designed for uniform lubrication. And the one-piece cast saddle bearings are built with large grease grooves for uniform grease flow and coverage.
So, when you know stronger is better - choose the best. The Fontaine® Stationary Plate Mount Fifth Wheel.
