VULCAN Security Chain and Lock Kit - Premium Case-Hardened - 5/16 Inch x 3 Foot (+/- 1.5 Inches) - Chain Cannot Be Cut with Bolt Cutters or Hand Tools

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.

Just what we needed. No bolt cutters will get through this chain! My only criticism is that we need more keys for the lock & you can’t get these duplicated.

So far so good.

Outstanding quality. I am very impressed with the quality of this heavy chain. I used it for a 2000 mile trip with a U-Haul cargo trailer, securing the trailer to the car hitch when I stopped overnight. I felt that it was a very secure chain, especially if you choose a proper lock to use with it. I would definitely recommend this chain.

The media could not be loaded. Love this lock so far! Works as shouldThis is the 3ft one

I bought this when I started riding my motorcycle because I wanted to chain up the bike while at work. It's heavy- heavy enough that I could easily use it for self defense! Probably 20-30 pounds of hardened steel.I appreciated that it has a fabric sheath, because it's easier to handle and doesn't scratch my bike's rims. The build quality seems titanic, I couldn't imagine a couple of guys quickly getting through this without some serious effort and 10+ minutes. I felt safe when it was on my bike.That being said, I started not bringing it along because it was so heavy, and I began realizing I didn't really need it for the area I was in.Pros:-Great build quality-Fabric sheath good for preventing scratches and pinches-Lock felt very solid, and was easy to open and close with the keys-Sturdy, compact bag for carrying was a bonusCons:-Heavy-The lock itself seemed easily pick-able. Very durable, but someone with a lock-pick set would make quick work of it.Would I buy it again?Yes, it's a quality product. Maybe a bit on the pricey side, but it felt good.

The security chain arrived on schedule and appears exactly as it was described. The chain cover should provide decent protection against scratching our 2 ebikes which it will secure while traveling with our travel trailer. Any real thief will know ahead of time that cutting is near impossible unless a power grinding wheel is used.Purchased a boron hardened Masterlock to lock the ebikes to our vehicle or around a tree etc. when not traveling.

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.
