The Roundlock
A perfect partner for your Protector chain
The Roundlock is our portable, tough and clever padlock. It has been designed to suit our Protector 13mm, 16mm and 19mm chains.
Awarded Sold Secure Gold, this tough little lock has a beefy 21mm shackle and a clever design, that allows the two sections to rotate, making it almost impossible to defeat.
The Roundlock also doubles as a motorcycle disc lock and they can be keyed alike, meaning you can buy multiple Roundlocks and open them all with a single key.
Often imitated, never bettered. We think the Roundlock is perfect portable theft deterrent.
