Kryptonite Stronghold Ground Anchor – Sold Secure Diamond Bike & Motorcycle Lock

The Kryptonite Stronghold Ground Anchor is a high-security, Sold Secure Diamond-rated anchor lock designed to form the foundation of any serious garage, shed or commercial security system. Ideal for securing bicycles, e-bikes, motorcycles and scooters, this permanent locking point provides maximum theft deterrence for both indoor and outdoor use.

Constructed from a 16mm hardened carbon alloy steel shackle, the Stronghold Ground Anchor delivers exceptional resistance to cutting, prying and leverage attacks.
