Schlage 12mm Cinch Ring Security Chain (No Lock)

I use this chain to lock up my mountain bike. I dont have any worries about anyone cutting through it (without power tools). Although realize this is not a very portable chain. Id be hard pressed to put it on my bike and take it anywhere, unless I was in a high-crime area.

This chain is a beast. It is very well constructed and highly recommended if it fits you application. Unfortunately it is too big to pass through the wheels of my cargo trailer. I am returning it because of its size but I would buy it again if I had a place to use it.

Very strong chain for all but the most insecure settings or expensive bicycles. Beyond this, you want to spend at least 3x the price to get much more. This is definitely a good $60 chain, balancing decent thickness with marvelous length and convenience that allows you to lock any large bicycle to even a telephone pole.

Dont cheap out, this chain is worth the investment. I use this is my bike chain with a good boron shackle lock; heavy as hell, but I just wear it like a sash. I wish it had a velcro strap at both ends of the sleeve instead of just the cinch end, but I understand the design decision.

This security chain is massive and heavy. I bought this to secure items at our RV when we are away from camp. Nothing is theft proof, but this chain will require them to spend a lot of time and make a lot of noise. And noise will wake up my two guard dogs, Smith and Wesson. Their bark is almost as bad as their bite!!! The chain is triple heat treated, 1/2 inch hexagonal sided links, and is made with manganese steel. The hexagonal links thwart bolt cutters as well as the extra strength from heat treating. And manganese steel is resistant to abrasive cutoff wheels. It can be cut, but time and speed are a thieves enemy (along with my two dogs, Smith and Wesson).

I use these to lock down my trailer and my motorcycles. These are monster chains!! Highly recommend!

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 duty chain. Im using it to secure a gas generator to a shed and more than enough length to secure. Because the chain is mounted in the back of the shed and under the generator, using a bolt cutter or grinder would not be impossible, but highly unlikely. I would recommend this product for this application. This is heavy so I wouldnt want to carry this around or use on a bike, but a motorcycle with storage bin would work.

As said in the title, the pictures on the product page, doesnt do this chain justice. Its some seriously heavy duty chain. The bottom chain in the attached picture is 3/8 grade 43 binding chain, and its dwarfed by the Schlage security chain. The welds and links on the chain I received were perfect. Some of the reviews said they looked inferior, but not so on this chain. The description says that the chain is 5, but the one I received is a good 6 longer than that. I would highly recommend this chain to anyone.

After having my storage unit broken in to 2 times I purchased this chain Kept thieves away. I saw attempted hack saw marks and bolt cutter marks that barely scratched the metal. I use it in combination with a very durable shrouded lock.
