Install New Weatherstrip (Side 1)

What happens here

Carefully position the new weatherstrip, with pre-started nails, against the door jamb. Ensure that the back edge of the rigid plastic/vinyl strip is perfectly even or flush with the main garage door trim or track. This alignment is crucial to ensure that the garage door will close properly without binding or leaving gaps. Once correctly aligned, firmly hammer in all the nails to secure the weatherstrip to the jamb.

Goal: Align and nail the new weatherstrip onto the door jamb, ensuring its back edge is flush with the garage door frame.
