Instead of using a helper bar to tighten the chains on the WD hitch you can use a ratchet. Not really an improvement from my perspective and I expect a longer half life on steel chain over a strap.
"“Like other RVers out there, hooking up my weight distribution system made me anxious,” said Product Developer Dave Gramlin. “I was tired of dealing with noisy, cumbersome and potentially dangerous chain systems that sometimes left me with bruises.”
Traditional chain systems can require raising and lowering the tow vehicle with a jack over and over to get the right tension. StrapTek adjusts by simply tightening or loosening the straps using a standard socket wrench, saving time and energy."
I have yet to be bruised by the hitch because I stand back a bit. Plus, once you have the right setting, just count your links. Maybe this would be good for users that have varying loads.
