SQUARE CHAIN CROSS-SECTION - 3/8 Inch x 6 Feet. The heavy-duty chain lock cross-sections are square, which does not allow bolt cutters to get a proper grip with a larger cross-section area and greater shear strength than regular round and hexagonal cross-sections. The case-hardened chain and the lock include a maximum security mechanism for ultimate protection.
PURE BRASS LOCK CORE - The solid forged brass one-piece body padlock has an exclusive shape and design that cannot be defeated with any normal burglary tools. The case-hardened security chain and core make it impossible to cut with bolt cutters or any other hand tool. If you missed keys, you literally need an acetylene torch to defeat this chain and lock kit.
MANGANESE STEEL MATERIAL - Heavy-duty motorcycle lock is made of high-strength manganese steel aka Hadfield steel, with a case-hardened, square link security chain that has an electro-galvanized finish for maximum corrosion protection, and it is fully covered in a wear pad to protect against scratching.
WIDE APPLICATION - The steel motorcycle disc lock is widely used in motorcycles, electric cars, bicycles, automobiles, tricycles, doors, grilles, and ladders. Security chain and lock kits usually are used as a bike lock, motorcycle lock, cable lock, trailer chain, and ATV lock.
