Chamberlain retail models - maximum door height of 10 feet

Chamberlain residential garage door openers (excluding Wall Mount) meet the industry standard to operate a 7 feet high garage door. If a garage door is higher than 7 feet, depending on your type of system, a chain or belt drive extension kit will be necessary to operate your garage door. Refer to the parts page in your product manual to order the correct extension kit.

If a garage door height exceeds 10 feet, please contact your local professional garage door installer. Garage doors higher than 10 feet are generally considered semi-commercial, these types of doors can include doors for workshops or RV's.

For help, locate your local authorized LiftMaster dealer.
