Schlage 12mm Cinch Ring Security Chain (No Lock)

This product is very similar to the Krytonites New York Noose chain, except its 3.3 feet instead of 2.5 feet. Combine with Kryptonites Evolution 4 lock and youll save about twenty bucks over the New York Noose, albeit sacrificing Kryptonites reimbursement guarantee if someone manages to cut the chain instead of the lock. Is that likely? In a word, no. The only way through it is with an angle grinder. Itd be easier to the cut the sign, rack, or whatever else the chain is attached to. This, assuming youre willing to carry the chain with you at all; its well over five pounds excluding the lock. I use mine to secure the bike to my trailer hitch when Im at stops while traveling. If I had to take something on a ride, Id opt for a U-lock.

After researching bicycle locks, chain reviews and bike theft videos, being on my 4th bike, living in NYC. Im happy to own this chain now. Its not too heavy, its what is needed to prevent it from being able to get clipped. Plus I got some exercise being able to do some bicep curls after unwrapping it. Along with the chain I got the Kryptonite Evolution Series 4 Bicycle Disc Bike Lock and feel my bicycles safe. Of course its important also where exactly and how to lock the bike. Theres still the seat and front wheel to consider. Perhaps another U-lock for the front-wheel.

Works great for my boat trailer.

It is impossible for a criminal to break this chain unless they were Superman mixed with Thanos. They would break the lock before this chain. And its uber heavy. Like heavier than any baby.

This is a heavy chain. Seems long enough for many applications. Another few inches would have been my preference but I believe it is sized on the metric system. I will use this only on certain rides and destinations and possibly combine it with other precautions. There is always a way for someone to get through any lock with the right tools and enough time. It will suit my needs just fine I am sure.

Thieves cut my big braided steel security cable on my 4 ladders like it was butter . My motion sensor camera saw my ladders , and then they didnt. i thought they were hard to cut but I was wrong ! So even though these chains are pricey, if they work it is worth it . I lost $500 worth of ladders in a few minutes . So I am trying to retain the ladders left on my truck with this chain . They are supposed to be a tough alloy , tripple heat treated and not round so supposedly harder to get bolt cutters around and cut . I have one of those hockey puck looking locks that dont give access to the shaft of the lock. So I guess they could get thru this chain with a cut off blade on a battery angle grinder , but that would take longer and make more noise . We will see . The druggies seem more desperate and with better tools than previously . It would help if Big Pharma wasnt pushing drugs way worse than the cartels do , and if the government agencies supposedly watching for the drug companies actually were , and the laws didnt favor the criminals, and the courts didnt let these guys out in a few days . These guys know how the system works . But I digress

The 39-inch version is 7lbs, not 5lbs as claimed. I am not a welder but the welds look okay to me.

I use this to lock up my new Ebike I named her Alice as in Alice In Chains. She is locked up with two of these heavy duty security chains and 4 locks. Security is also backed up by the security camera system, alarm system, and a Glock 9 for safe keeping. Cheers

At 6 pounds 12.3 ounces measured on my kitchen scale which is accurate to 1/10 of an ounce its a hefty chain. The links are 6 sided which is suppose to require a greater amount of pressure to break the chain with a bolt cutter because the pressure of the bolt cutter blades are spread over a broader area unlike round links. Each link is 12mm side to side measured with my micrometer which is accurate to 0.001 inches which I then converted to mm. The measurement in inches was 0.474 inches so its not quite 1/2 inch although its advertised as 1/2 inch. The chain does measure 39.5 inches in length including the cinch ring. My criteria in purchasing a chain was to have something that would most likely deter anyone wanting to steal my bicycle. The name of the game is deterrence. No lock or chain is full proof. Most thieves just want to get in and out quickly. They want the easy job, not the job that requires a lot of effort unless the pay off is also great. I decided that the minimum diameter of each link would be 12 mm after watching many Youtube videos and researching the cost of chains that are larger in diameter but of course would also weigh more. Twelve millimeter thickness seems to be the minimum thickness that requires the largest bolt cutter and is still nearly impossible to break. Its amazing how much more the chains weigh with just a small increase in diameter. I have not tried to cut this chain with a hack saw nor have I tried to break it with a bolt cutter. I did find a video by a chain manufacturer trying to break their own chains with a very large bolt cutter leveraged against the ground using his full body weight. He couldnt break the chain. Given enough time Im sure you can cut through this with a hack saw but again the thieves want to be out of there quickly. You can find a cordless angle grinder being used to cut through a 12mm chain in less than 2 minutes because it takes 2 cuts to release the chain. No chain will stop an angle cutter. You cant stop everyone. You can only deter the majority. If someone wants what you have bad enough they will have the determination to find a way to steal it. Deterrence is the name of the game. I also purchased a Kryptonite Evolution series 4 U-Lock to lock the chain and will post a review of it. Its not about the destination, its about the journey.

This chain is HUGE. Certainly fine for my needs. Only downside? The weight. But no stars off for that.. Nice welds also.
