Martin Garage Door Opener DC3700HD

All Martin garage door openers are powered by quiet DC motors. Although DC power is generally measured in Newtons of force, the DC3700HD has horsepower comparable to a 1 HP AC model. The DC powered system includes soft start and stop operation for less opening and closing noise and longer garage door life.

When installed with a Martin garage door, Martin openers come with Soft-Touch Reverse Technology™. This safety feature stops and reverses the door when closing, or stops the door when opening if the door encounters a soft touch interuption. With this optional feature installed, the need for photo eyes is eliminated on doors up to 420 pounds.

The Martin “Smart Computer” control panel is a user friendly feature on the power head that helps you set the travel limits and adjust the force setting if necessary. The Martin DC3700HD is dealer installed and carries a lfetime warranty on the motor, belt, parts and rail.
