Locate the mounting screws — On the door edge (in the inactive leaf), you'll find screws holding the header bolt assembly in place.
Remove the screws — Undo all the screws securing the header bolt.
Slide out the assembly — Once the screws are out, the header bolt assembly can be pulled out from the top of the door

Replacement / Reinstallation Steps
With the old assembly removed, prepare to insert the new header bolt from the top of the inactive leaf.
Make sure it aligns correctly, then secure it using the supplied screws.
If included, break off any assembly tabs as indicated in the installation instructions
