What to look for
Motorcycle Grade Strength
These locks utilize heavy duty chain links suitable for motorcycles and scooters. The thickness provides a significant deterrent against manual cutting tools.
Weatherproof Construction
The stainless steel materials are specifically chosen for rustproof performance. This makes them ideal for permanent outdoor gate or fence installations.
Comprehensive Key Set
Providing four keys ensures that fleet managers or families have sufficient access points. This reduces the risk of lockout if a single key is lost.
Versatile Utility
The 39.3 in length allows for flexible locking positions. It easily wraps around large posts, bike frames, and scooter decks.
