I'm thinking about applying for a patent on a system I came up with to set the tension on the trunnion and round bar springs of a weight distribution hitch. The patent road is a very expensive road to travel on. I am looking to see if there would be any interest in such a product. I would like to list the advantages of this system....#1 This system that I have designed sets the spring bar tension without the need to raise your tow vehicle. #2 Thus reducing the hitch time to a fraction of the norm. #3 Once you have set your tension and raised your jack, often you find that you need more tension on the springs.....this can now be adjusted in seconds without the use of your jack. #4 This system will affix to the A-frame of your trailer without interference from the propane bottles. #5 This system is silent...there will be no more popping and cracking noise from the chains and the snap-up hooks when cornering. #6 There is far better sway control than with snap up hooks and chains. #7 Last but certainly not lest...this system has a 12 to 1 safety factor rating. Necessity is the mother of invention. After almost fracturing my wrist on a snap-up hook release, I decided there had to be a better way. Your feed back with this system would be greatly appriciated.
