VULCANSecurity Chain - Premium Case-Hardened - 3/8 Inch x 3 Foot (+/-2 Inches) - Chain Cannot Be Cut with Bolt Cutters or Hand Tools

Very solid...bought this after my scooter got stolen and I bought a new bike. Very impressed with the quality...have the 6 ft and it Heavy lol.

This is a great combination. The chain is harder than bolt-cutter jaws --see various youtube videos on Pewag security chain-- and is coated to prevent rust. The cloth cover is a welcome addition. The padlock fits the chain perfectly in a way that prevents bolt cutters from reaching the shackle of the lock. The lock is apparently difficult for anyone other than an expert to pick --see youtube videos on picking the Viro Panzer-- but spare keys can still be made reasonably cheaply. The padlock is armor-plated (even on the sides, which apparently is an improvement over earlier similar Viro locks that exposed softer brass surfaces on the sides).Together, this lock and chain give a security mechanism that defeats even very strong bolt cutters, which is what I was after. Obviously it can be defeated by an angle grinder (as any lock or chain can), and possibly by drilling out the lock (although I haven't seen that tested). However, attacks with power tools would be somewhat difficult without putting the lock or chain in a vise, and more importantly would cause huge amounts of sparks and noise for over a minute. That's about the best security that it's possible to achieve with just a padlock and chain (given the amount of research that I was willing to do).The price (from Ratchet Strap Warehouse) is great too -- significantly cheaper than I was able to find equivalent secure lock and chain elsewhere.Both of the padlocks that I have received have worked very smoothly, with no sign of the stiff/wedged shackle that was reported in one review on Amazon. But just in case, I plan to occasionally squirt some WD-40 into the keyway and shackle housing.Note that both the lock and the chain are very heavy, which means that the 3' chain might sometimes be the better option. E.g. I ordered two of the 6' chains (and locks) for securing vehicles and trailers, but I also want to secure a gate that is in frequent use. As I don't need 6' length of chain for the gate, and the weight of 6' chain makes it somewhat unwieldy, I just ordered a 3' chain (with the same lock).Update on 9/11/17: Instead of WD-40, I've learned that it's best to use non-stick Teflon as a lubricant for padlocks. I'm using this: https://www.amazon.com/gp/product/B003UTX0R8/Also, my earlier statement about "spare keys can still be made reasonably cheaply" is still yet to be verified, as none of our local locksmiths (in WA, USA) had the necessary blanks to be able to make keys for the Viro locks. I'm still trying to find a way to obtain spare keys.

I've had this chain about two years now, I use it every once in a while to lock up my motorcycle. It's worked well for me, the lock is robust and a nice piece of Italian manufacturing. The bag it comes in is handy for storage, and the sleeve on the chain protects it.I wasn't thrilled with how the galvanized coating had held up on my chain, so I emailed them. Some links were fine and some were losing their coating after only rather light use (my area being humid probably doesn't help). The chain with the minor galvanizing issue is pictured above.They immediately responded, and after confirming my purchase sent out a whole new chain with new sleeve and bag. That's almost unheard of these days. Being able to quickly get a response from a domestic based employee and having them send out a new one that arrives within days is a major plus. I'll continue to support this American company for all my chain and lock needs from now on. Companies that back up their products like they did need to be rewarded, and I will happily pay a slight premium for the peace of mind knowing the produce quality locking systems that they stand by.

Exactly what I was looking for and as described in the product description. Heavy duty and it is exactly what i need for my e-bike. The weight is significant so you need to consider that in your purchase because you have to decide how you will carry it on the bike while riding - I use saddle bags and carry the lock/chain in there.

Super high quality. Nothing more I could ask for in a chain lock set. Three keys instead of just two is nice as well. Glad I purchased.
