Craftsman CMXB4230 Ultra-Quiet Smart Belt Drive Garage Door Opener with Wi-Fi and Battery Backup
This Craftsman garage door opener is for the homeowner who wants to simplify daily routines and secure their space without hassle. While many focus on basic access, this model brings quiet reliability to garages near bedrooms or living areas, so you can come and go without disturbing the family.
The ultra-quiet operation uses a DC motor and belt drive to open your door smoothly, almost silently. You will appreciate this when you arrive home late or leave early without waking anyone. With integrated Wi-Fi, the myQ app lets you check and control your garage door from anywhere, giving you peace of mind if you forget to close it. The battery backup ensures access during power outages, so you are never locked out. Two remotes provide easy in-vehicle control, and the 2-light system illuminates your entire garage for safer entry at night.
