Sears.com suggests installing Craftsman belt-drive garage door openers in garages that have rooms above or near them, in order to minimize the noise disturbance during operation. The Craftsman garage door openers that are chain-drive are advertised as being more powerful than belt-drive openers and more dependable.
The battery-backup feature is only equipped in Craftsman belt-drive garage doors. The battery backup in these garage doors prevents the opener from dying during a power outage.

Both the belt- and chain-drive Craftsman opener models come with 3/4 horsepower options as well.
