Smooth Opening and Closing of Even the Heaviest Doors
Many garage openers simply cannot accommodate large, heavy, or antique garage doors. In the past, owners of older homes had to manually lift and open their doors themselves or had to park elsewhere to avoid the hassle.

Reliable, Whisper-Quiet Operation
Winner of the Good Housekeeping Seal of Approval, the PD752D garage-door opener is the perfect solution for hard-to-manage doors. Backed by a lifetime warranty, the finely-tuned, yet ruggedly designed 3/4-horsepower motor with industrial strength chain provides the synergy needed to open heavy garage doors quickly and quietly.

In fact, thanks to its exclusive Motor Vibration Isolation System (MVIS), the PD752D is whisper quiet--no clanking, crunching, or squeaking mechanical noises as the door opens and closes.

Additionally, an enclosed gear case provides continuous lubrication and protection for longer life and smoother operation.

Fast, Easy Installation in Just 60 Seconds
Quick and easy to install, this system arrives with five railing sections that assemble into one long piece. Clear, easy-to-read instructions guide you through the process step by step--in just one minute you'll have a completely assembled unit.

For added convenience, the PD752D has a light that delivers 200 watts and has an adjustable time delay so you can enjoy illumination when you need it.

Advanced Safety and Security Features Protect Against Accidents and Theft
The PD752D is equipped with safety features that protect users from accidental closings, as well as from break-ins and theft. First and foremost, auto force-sensing technology constantly monitors the garage door area and adjusts forces according to temperature fluctuations, floor height, and door track movement.

Additionally, the included protector system features safety sensors with Rapid-Snap brackets that project an invisible light beam across the door opening and automatically reverse the door if anything interrupts the beam while the door is descending. For added peace of mind, sensing technology will stop the door from closing if contact is made with a person or object and opener lights will turn on automatically if the infrared beam is broken.

To guard against someone discovering your secret code, the PD752D's Security+ anti-burglary protection uses rolling technology and sends a new code every time you use your remote control. For an additional layer of protection, PosiLock theft protection ensures that once the door is closed, it stays locked. An added bonus, a manual release handle can be used in case of power failure.
