Security Chains

Heavy-Duty Security Chains for Motorcycles and Bicycles

Pragmasis Protector security chains are designed to provide serious theft protection for motorcycles, bicycles and other valuable equipment. Manufactured from specially selected hardened alloy steel, our chains offer excellent resistance to common forms of attack, including bolt croppers, saws and hammers.

Available in 11mm, 13mm, 16mm, 19mm and 22mm link thicknesses, the Protector range offers different levels of security, weight and portability.

Which Security Chain Should I Choose?

• 11mm: A relatively lightweight option for cyclists and motorcyclists who need to carry their chain regularly.
• 13mm: A popular compromise between security, weight and practicality, suitable for bicycles and motorcycles.
• 16mm: A substantial security chain for motorcycles, particularly well suited to home and garage security.
• 19mm: A heavyweight option for motorcycles stored at home or in higher-risk locations where portability is less important.
• 22mm: Our heaviest Protector chain, intended for demanding stationary security applications.

Already own a Protector chain? We also supply replacement security chain sleeves to help protect your motorcycle or bicycle's paintwork and keep your chain looking its best.

Standard or Noose Security Chain?

Our standard chains have conventional links at both ends, while our noose chains feature an enlarged end link that allows the chain to pass through itself. This provides greater usable reach for a given chain length and can make it easier to secure your motorcycle or bicycle to a fixed object.

Complete Your Security Setup

For the best protection, secure your chain to a substantial fixed point, such as a properly installed ground anchor, and use a compatible high-security padlock. Always check lock compatibility before choosing your chain, as thicker links and noose-end designs may require different locks.
