Thank you for contacting us. Our Installation & Maintenance Manual provides instructions on how to reinforce the top section for attaching a garage door opener. Depending on the Clopay garage door model and garage door size, a horizontal reinforcement might also be required along with an opener reinforcement bracket. The bracket that comes with an opener cannot be used with a Clopay garage door as it would void the warranty. Please refer to the Installation & Maintenance Manual and if you have any questions, please contact our Consumer Services Dept at 800-225-6729. Thanks The Clopay Team.
