With the single stud fitting, made of metal, you quickly create a secure fastening point. The large ring accepts a wide variety of hooks, snaps and straps and can be mounted in airline rails.
The spring-loaded plunger-style mechanism is easy to use: place the thumb in the ring and push it down while lifting the clip with your index finger and middle finger. Place the bottom disc in the desired round opening on the track. Slide the fitting in both directions so that it lies halfway between two of the openings of the tracks and let the clip on both sides of the fitting fall into the round slots on both sides of the stud.
