A: Hi PCCB. The top roller goes into the top track and the rest of the rollers follow along in the bottom track. Thanks for shopping the Home Depot, the Clopay team
A: Hi Kevin, If you use the low headroom kit and do not have an opener on the door the bottom of the door may hang about 3" in the opening. If you use an opener you are able to pull the door completely out of the opening. Thanks for shopping the Home Depot, the Clopay team
A: Mitch, we recommend a minimum of 12" of headroom to install a garage door. If you are installing a Garage Door Opener, we recommend a minimum of 15" of headroom. Thanks for shopping The Home Depot, The Clopay Team
A: There are install instructions that you can download that will give a dimension and also how to measure. I ordered the low headroom kit for my remote location install. It turns out that i did not need the low headroom kit. If you are creative and handy order door if your installation is close to what the install insructions say you need. Then just start the install and see how it goes before ordering a low headroom kit.
