DescriptionShipping & Warranty

Protect from Theft. Packed with features OnGuard locks earn the highest safety ratings with quad-locking mechanisms, bump-resistant cylinders, and hardened steel shackles and chains.

Hexagonal and square links present more hardened surfaces than round links making sawing and cutting virtually impossible. Titanium surface hardening vastly increases cut and saw resistance.

Protect from Damage. On the outside, OnGuard's locks are fully coated to protect your bike from scratches and to shield internal parts from the elements. Embroidered nylon chain covers won’t crack or peel for long-lasting appeal. Hook and loop tabs keep cover in place to help protect paint and finishes.
