Never too many locks... and these are 40 MM. in size and are keyed alike. (Four locks in a set). Perfect for going thru larger chain links or locking cages or larger "D" rings to a chain loop. These are laminated steel padlocks and are tough.

I hate trying to find the exact key for a number of different locks... and I use a lot of locks when playing. That's why having 4 of these larger locks all with the same key is great. The blue plastic sleeve at the bottom of each lock will slip right off if you don't want that color on your lock.

A nice set of this size lock, keyed alike and at a great price.
