OKG High Security Chain Features

HOOK-N-LOOP SLEEVE
Durable, weather-resistant, highly flexible embroidered sleeve with hook-n-loop fastener allows compact coiling and protects bike, motorbike surface.
RESISTANT TO NUMEROUS CUT TOOLS ATTACK
12mm SIX-SIDED chain links made of triple heat-treated boron MANGANESE ANTI-CORROSION STEEL for extreme strength, hardened throughout the entire thickness, rather than simply having a tough inner core or hardened outer-coating. Narrower inner width of individual links prevents bolt cutters, bolt croppers and leverage attacks.
COME WITH CHAIN BAG
Includes a carrying bag for easy storage and transport. GREEN ZINC plating prevents rust and corrosion and is ideal for indoor/outdoor.
Security lock chains from OKG are ideal to secure high-value items
OKG brand anti-theft chain is not easy to open with bottle jacks or lever tools, and it is also difficult to cut with electric or hand tools. So, the negative reward for you enjoying huge security gains is: they are very heavy!!! Therefore, you must find the best balance between weight and safety before buying.
OKG MOTORCYCLE LOCK CHAIN uses the noose chain design to provide more effective usage length. You don’t need to worry about the chain length when you select security chain because it can be used with most high security padlocks.
OKG Heavy Duty Security chain is made of triple heat-treated boron SPECIAL ALLOY STEEL with a special anti-corrosion coating which makes them ideal for outside use. The links are not round like on common chains, but are hexagonal shaped which is a lot more effective against attacks with tools. This chain also features a nylon chain sleeve to prevent paint work and chrome from scratches and damage.

Great, heavy duty chain. Comes with its own carry bag. Well made, but it weighs allot. I bought this to lock bikes at my home. Kind of heavy to carry on rides.

I used this chain to attach a piece of art to the ground in my garden so it wouldn't get stolen. It's a good chain for that. It's very big and very heavy. It might be too heavy for a bike chain as carrying it around would be burdensome. It's a bigger and more impressive chain than I expected. It's very beautiful in fact. However, if you really want your bike protected and you don't mind a heavy chain then this is going to work for you.

THERE it sits in the back of an old 2003 FORD F250 heart and soul V10 pickup with the words faded "NEW HOLLAND" on the utility bed (An old service truck for tractors in Klamath.The wind is HOWLING at the moment as the old truck sits in twenty five degree Fahrenheit... The lock holds my chained up spare for those extreme condition that might arise indeed, and forthwith tomorrow's rising of the winter-sun.There the golden lock hold my tire and wheel secure and unstain't against the elements. Golden and fabris black still glinting a smile for hot summer's apocalypse. There the golden lock holds that whell secure. Even the lock has tightened and needs oil and gloss, but the lock still shines there under a rabbit that lives under the truck between when the old :New Holland goes to the dump and to the modern metropolis of Klamath Falls and even A'West to Medford a'strengthen't with this adorned and PRETTY lock.

Sure, it’s heavy. But that’s what you want when it comes to protecting your expensive motorcycle or scooter. Came with a nice carrying case which is handy. I’ll probably buy another one for my other motorcycle.

Grosse chaine pesante, semble dure à scier (fera du bruit et prendra du temps)...mais attention, elle vient seule, SEULE, sans cadenas. Il faut acheter le cadenas en plus. Sur ce point, je me suis fait piéger. Je croyais qu'elle venait avec cadenas, comme sur une des photos. Parfait pour moto et scooter devant la maison.

This is a solid/heavy chain and to the extent that you don't want thieves cutting the chain, it's likely to deter them more than a normal chain which is easily cut. Comes in a carry bag which is pretty necessary. This thing is heavy and slippery when you try to just carry it. It's much better than any comparable I've encountered. Great product and Seller.
