Makes a nice quality sounds when engaged.

These roller catches are a solid alternative to the metal, builder grade ball catches. They are more difficult to install as the prep work on the door and jamb takes some time to get a system going. All in all, for $15, a nice product. Would recommend.

De muy buena calidad

Great product! Made well, and worked perfect for holding solid core doors closed on 3-elevations for residential elevator applications.

Heavy duty. Adjustable, very important. Very nice. I ordered a second set for another door.
