Chamberlain Whisper Drive Plus Belt Drive Garage Door Opener

New in-box Chamberlain Whisper Drive Plus garage door opener system. It's a 1/2 H.P. belt drive with EverCharge Battery Backup. This HD800D model includes a garage access system. It's designed to lift even the heaviest garage doors quietly! This is a robust high-end opener. You'll find flimsy, noisier ones for more than I'm selling this one. Includes two 3-button remotes, motion-detecting control panel, wireless keyless entry, and remote light control.
