Fontaine Fifth Wheel used computer-aided design to develop the smaller footprint of its LWB lightweight slide bracket assembly that uses steel reinforcement in key areas to provide greater durability and strength. The LWB accepts a variety of Fontaine No-Slack top plates, including model 6000 stamped steel, model 7000 cast steel and model 7000CC cast steel, low-lube; mounting heights range from 6¾ to 10¼ inches.
The LWB’s Quad-Lock four-point locking system is designed to increase the locking surface area to provide greater stability and improved wear characteristics. The assembly’s two-inch increment positioning capability is engineered to provide greater versatility for improved payload distribution, while its greaseless bracket liner facilitates consistent lubrication and reduced wear. The LWB is rated up to 55,000 pounds vertical load and 150,000 pounds drawbar pull rating.
