How do I install 10-563, I have one that is broken inside!

Thank you for your patience in this matter. I hope I can help you replace this latch!
The first thing you want to do is remove the old, broken latch. To do so, you'll have to drill a 3/8" diameter hole through the center of the "female" knob approximately 1/2" to 5/8" deep. The "female" knob is that which is on the inside of the stall. You can see what it looks like by looking at either our 10-556 or 10-557 knob assemblies. You will have to replace these knobs once you've drilled it out, as they are not meant to come apart.
Once the latch is removed, insert the "male"--or outside--knob on the outside of the door through the 10-563 latch. Then, align the pins and holes and test the latch using only the "male" knob, to make sure that it's working properly. If is is, then snap the "female" knob into place.
Please remember that once these pieces are engaged, they will not come apart.
