Average Reviews:
(More customer reviews)I was bought a 5019LP recently, and was curious about how strong this chain really is - so I decided to test it for myself.I figured that it was worth losing a link of length to know if it's as strong as they claim.Yes, I'm an enginerd.
I took the 5019LP to a nearby hardware store and grabbed the largest bolt cutters I could find (a 36", $50 unit).I found a quiet aisle and put the final link (the regular link end, not the big link) in the jaws, braced one handle of the bolt cutters against the floor and then started whaling on the other handle.I threw all my weight against it, bounced up and down on the handle, tried some different positions on the chain and in the jaws, but the chain did not cut.There was only a minor indentation on the link (<0.5mm): the blades of the bolt cutters were actually dented worse.(Sorry hardware store!)
So I conclude that it really is made from hardened high strength steel.I've done this kind of test before on conventional hardware store chain of similar diameter, and those chains were indented much more.Speaking of diameter, note that the links are 10mm in width, NOT 12mm like Amazon says.I just measured 'em.
So I am confident that this chain will stop the neighbourhood punk with typical bolt cutters (the ones I tested with were the top size in the in-store range and cost $50).If he has really nice bolt cutters he might cut the 5019, but such cutters aren't even available where I live.(There are some online for $140 that are rated to cut up to 14mm chain, which is too heavy to carry).If he uses a hacksaw he'll probably get through eventually, but he'll be there for a LONG time.I haven't tried the freeze and smash trick, but I imagine that it'd be hard to brace the chain well enough to transmit a good enough shock to it.And if he shows up with an oxy-acetylene torch, a plasma cutter, or industrial hydraulic cutters, he'll get through ANY chain.
I believe that this chain offers excellent security and decent portability.At 8 pounds (including the lock) (3.6kg) it's a bit heavy, but not too bad for a bike.It's like carrying a laptop with a charger.Thicker chains are too heavy for my security needs.
