That's the same as the chains of a typical two-bar WD with snap-up brackets. If someone unfamiliar with the setup of that specific trailer and tow vehicle hooks the chain onto the bracket at the wrong link, they will have the wrong preload on the spring bar.
The same thing applies to the nuts of the Andersen No-Sway: if they are tightened to the wrong position, the load distribution will not be as intended when set up.
There are
other WD systems with a winch arrangement for the linkage from trailer frame to spring bar; for instance, the
Blue Ox SwayPro uses "rotating latches" (which could probably be used with other brands of two-spring-bars-and-chains WD systems as well), and the Hensley Arrow uses telescoping spring bar jacks (as does the ProPride copy). From Australia, there's the
Trojan Load Leveller HD, which has telescoping jacks, a sliding bar design (like Equal-i-zer, Fastway E2, etc), and multi-leaf spring bars... it looks better thought-out than any of the stuff I've seen from North America.
It would certainly make sense to mark the strap or note the final length in some way, to ensure repeatable application with this system. It's a manageable issue.
