Viro Monolith Lock For 1/2" Security Chain

Super thick.

Great for 1/2" chains. It actually opens up all the way which makes getting 2 links in and out easier. Not saying it's lose at all. Just a solid lock with an upgraded inner lock set-up and key. I use it for the e-bikes.

Works as advertised

Smooth operation in conjunction with the 1/2 inch square security chain. More worried about someone picking the lock then trying to destroy the lock. It is beefy.

Insane Quality/Will buy Again

Insane quality lock, big and heavy, sturdy, feels safe to lock up and leave behind. Would buy again in a heartbeat and probably will for other gates of ours in the future.
