What to Compare Before Buying
- Measure the full path around the item and the anchor point. The usable loop is shorter than the chain’s total length once it is routed around them.
- Check whether the 4 mm links fit through the openings you intend to use, and whether the padlock can close around the chain at that position.
- Consider the security needs of the place where the lock will be used. The stated dimensions and materials do not provide a security rating.
What Is Included
The listed set contains one padlock and two keys with the chain. Keep the keys accessible wherever the lock is used.
Before You Decide
Confirm that 500 mm provides enough reach for your intended route, that the links fit the available openings, and that the padlock can close at the chosen locking point.
