This takes 5 mins to do and costs nothing. It keeps the garage door pressed up against the outside rubber seal so cold air is not blowing through the gap. I do this to the doors in my heated shop every fall and then undo them every spring. Now the heater runs much less!
Note: these doors are only opened a couple times/month during winter and they don’t have a power door opener on them. Tracks on my doors are not adjustable, plus the track goes down into the concrete floor.
