Best Security Chain Lock Set for Heavy Duty Use

The DocksLocks heavy duty cinch style security chain is available in multiple sizes - 3ft, 6ft, or 10ft. Constructed from chrome alloy carbon steel, the chain is weatherproof and includes the DocksLocks short shackle U-lock. This chain can be used to secure a variety of items, such as motorcycles, gates and fences, bicycles, kayaks, scooters, tools, tool boxes, garages, ATVs, generators, golf carts, mopeds, coolers, ladders, and sports equipment, providing superior security and anti-theft protection.

The premium heavy duty chain is engineered for maximum theft protection, designed to secure valuable property from would-be thieves. The chain is made from AISI 1035 chrome alloy carbon steel, a water-resistant alloy steel with a metal composition including carbon, manganese, and chromium, which increases the chain's strength, hardness, and durability. The chain is further hardened through a triple heat process with advanced welding technology to enhance its cut resistance.

To protect the secured property from scratches and damage, the chain is wrapped in a thick exterior weather-resistant nylon sleeve. A carry bag is also included for easy storage and transport when the chain is not in use.

The chain's maximum security features include its composition of premium AISI 1035 carbon steel, which significantly increases the chain's wear resistance and hardenability. The triple heat treatment further maximizes the chain's hardness, ensuring ultimate strength and maximum cut resistance. This provides protection against attacks using hand-powered tools such as bolt cutters, and strong resistance to cutting, shearing, and lever attacks, keeping the property secure and safe.

Designed for all-weather performance, the chain is ideal for indoor and outdoor use. Constructed from AISI 1035 steel, a water-resisting chrome alloy carbon steel, the chain is also galvanized and treated with a powerful corrosion-resistant sealant to provide a significant level of salt spray protection. Each chain is certified through a minimum 96-hour strenuous salt spray test, ensuring superior durability.

The chain's multi-function cinch style noose security system design features a special O-ring that allows the chain to be secured using a cinch style, effectively doubling the working length of the chain and maximizing its application. This cinch style also reduces the required chain length, thereby reducing the storage and transport weight of the necessary size chain that meets the security needs. The cinch style is recommended for use with U-locks, disc locks, and padlocks, and is the best and most efficient choice for securing property.

Included with the chain is a heavy-duty combination lock, the DocksLocks short shackle U-lock, which offers strong cut, pry, and lever attack protection, while being compact and lightweight. The 12mm chrome-plated hardened steel shackle provides maximum theft protection, and the chrome plating and zinc alloy body with PVC coating ensure maximum weather resistance and protection against the elements.

The chain's specifications are as follows: chain thickness - 8mm; length - 3ft; interior diameter of chain link - 15mm; interior diameter of O-ring - 40mm; and the chain metal type is AISI 1035 chrome alloy carbon steel.
