What to Compare Before Buying
- Reach: Compare the 3 ft length with the route around your bicycle or other item and the object you plan to secure it to.
- Chain size: The chain is 4mm thick. Do not treat this measurement as a guarantee of resistance to theft or cutting.
- Code operation: The code is settable and resettable. Check the product instructions for the exact setting and resetting procedure.
- Use context: Consider how long the item will be left unattended and the security conditions where it will be parked.
Important Limitations
The listing cautions against leaving a bicycle locked outside for long periods, especially in high-crime areas, and notes that no bike lock is completely secure. This lock’s chain thickness and combination mechanism do not establish a particular security grade or level of theft protection.
Before You Decide
Confirm that 3 ft provides enough reach for your intended locking point, that a 4mm chain suits your requirements, and that you are comfortable using a combination rather than a key.
