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.
