According to Fontaine, this new product features the light-weight 6000 No-Slack top plate mounted to the light-weight Fontaine NWB sliding bracket. The net result is about 60 lb. lighter than the competition plus it features the added benefit of Fontaine’s No-Slack technology so the lock automatically self-adjusts to trailer kingpin variances for a smoother ride, lower maintenance costs and longer component life. No change was made to the No-Slack lock components so customers can count on the same great performance they have always depended upon with Fontaine and parts are interchangeable with older models, the company says.
“We’re really proud of the engineering team that made this happen,” says Mike Randolph, vice president of sales and marketing for North America. “Using Finite Element Analysis technology and strategic placement of high strength alloy steel, they accomplished this goal without sacrificing an ounce of performance, durability or load rating,” concluded Randolph.
Fontaine says the 6NWB is rated at 50,000 lb. vertical load with a drawbar pull rating of 150,000 lb.
