swing door top plunger

I have several doors that are swing door going into baths and closets that have a ball with a spring underneath. I have attached a photo. some are missing.

Here are some photos;

Closet photo 1 - top of jamb where the little ball strikes the plates and hold the door closed.

Closet photo 2 - top of door with threaded hole where spring drops down into it first, then ball, then threaded cap that holds it in place. Ball sticks up a little and catches the type of strike plate on header.

Please keep in mind that these are double swing doors. Not bi-pass or bi-fold but hinged swinging doors.

hope this helps - I really appreciate the help

The type of catch "bullet catch" is right, but I have a different design. I included some more photos and drawings. I really, really appreciate your help.

I also have several ball catches that have come apart like the original picture. Can you tell me the thread size of the 10-057 collar that contains the spring and ball? I'm referring to the threads on the collar in the first picture of this thread. The threads on mine are approximately 11/16-16 and I'm hoping I can simply thread a 10-057 assembly into my existing press-in door housing as shown in the second picture of this thread.

Thanks

I have what appears to be an identical design in my house. I have some where the screw-in piece no longer holds the ball. The 10-057 picture looks very similar. Is it possible to unscrew the inside piece (I use a quarter to press down the ball and engage the two slots in the top of the threaded piece). If this really is the same, it would be much easier to just unscrew the threaded part and discard the housing (since I already have the housing installed in all the doors).

Thanks

Thank you.

If the guts don't fit my housing, then I'll just have to replace the housing too. The chance for saving that effort is certainly worth trying.

Yes, it did work!

I think the housing was slightly cross-threaded as I had some difficulty getting the new piece to go in straight. I took the ball and spring out and tried just the brass threaded part, but even that took some trying before I go it. Once I knew that it really did fit, I was able to do so with the spring and ball in place.
