Step 6 · Install Closet Bolts and Wax Ring
Slide the new closet bolts into the slots on the newly installed flange extender, with the threaded ends pointing up. Position them parallel to the back wall. Next, take the new wax ring and place it on top of the flange extender, centered over the drain opening. Press down gently to create a slight tack, holding it in place. Alternatively, some plumbers prefer to install the wax ring onto the outlet horn on the bottom of the toilet itself.
