 Reliability and Convenience Features:
Proven Performance
Similar in design to our commercial jackshaft door operators, this model is designed with years of performance testing and proven reliability.
3-Button Security+ Remote
With rolling code technology, you are assured of the highest security every time you push the button. The code automatically rolls over to any one of 100-billion new codes, never to be repeated. Operates up to 3 garage doors.
Cable Tension Monitor
Specially designed to maintain accurate tension and eliminate "calbe throw," which occurs when the cable slips off the drum. This ensures dependable performance and virtually eliminates unnecessary service calls.
HomeLink Compatible
The in-vehicle universal remote control. See your automobile dealer for availability.
 Included Security and Safety Features:
Power Lock
Once your garage door goes down, it's securely locked with the power lock. Similar to a deadbolt, it ensures the door cannot be forced open.

The Protector System*
Projects an invisible light beam across garage door opening. If interrupted while the door is closing, the opener reverses before making contact. If beam is obstructed, door will not close.
For additional safety, the light automatically goes on whenever the beam is broken.

Manual Release Handle
In case of power failure, this feature releases the garage door for manual operation. One pull disengages the opener from the door and another pull re-engages the opener.
*WARNING: Garage doors and openers can be dangerous if not properly installed, tested and operated. Children should be supervised by an adult whenever in or around the garage area .
 Installation Features:

Wall-Mount Installation
Mounts on left or right side of door. No rails to hang, it simply mounts on the wall and attaches to the garage door torsion bar. Unit requires an electrical outlet within 6 feet.

Patented Absolute Positioning Technology
The newest technology in garage door openers, our patented design allows the electronic limits to be extremely accurate, even after a power failure.

Exclusive! The Smart Garage Door Opener
Lets you electronically program additional remotes or a keyless entry from the Smart control panel or the powerhead.

Quick-Connect Terminals
Push-in wiring for quicker installation.

6-Foot Power Cord

Push Button Limit Settings/Automatic Force Sensing
Allows for faster setup. Auto-force feature constantly monitors garage door system and adjusts forces to temperature fluctuations, floor height and door track movement.
