I've read that one of the advantages of square links is the fact that bolt cutters cannot get a proper "bite" on the link to break it. I need the capability of a chain with a loop pass-through, but now that we've introduced a traditional round link into the equation, doesn't that in fact become the "weak link in the chain" because a round link that is more susceptible to bolt cutters? Additionally, if the square links are 1/2 inch, what is the width/strength of the round pass-through link? If it's rounder, thinner and more susceptible to bolt cutters, it kind of negates the strength of the entire chain overall. Any input or information you have on limitations of the round pass-through would be greatly appreciated.

It is true that the modern trend is to have a square/angled security chain to prevent bolt cutters from getting a good bite, but size is also a factor. If the chain is large enough and hard enough, even if not square/angled, then it will still be very tough to cut. In regards to the ring material, we have had this question before and Abus has confirmed the ring is plenty tough. Its dimensions are 0.55" Thick x 2.05" ID and 3.11" ID (approximate dimensions, measured by hand with calipers).
