Expensive lesson to learn
I hired a garage door tech to come to my house to install this garage sweep. After he installed it, my garage door would not close. Evidently the rubber is so hard that it makes my garage door bounce back up. Unfortunately, the garage door tech had cut it to make it fit on my garage, which was 8 feet, not 8‘2“. So I was unable to return it. Very expensive lesson to learn. You really should have it in your write up that the rubber is very hard and may cause the sensors of an electric garage door to bounce back up. This is something your customers should know before purchasing such an expensive item.
