Cabinet door - how to tighten catch

One of the catches on a cabinet door seems loose when you open the door. I thought there was a way to tighten the catch - is there?

On edit: To clarify, it is very easy to open the cabinet door. What I would like to do is pinch the rollers together so it is harder to open the cabinet door. I hope this makes more sense.

Here is a picture of the double roller catch that we have.


Thanks for your help!
