There is a choice not only between the quiet belt drive technology and the durable chain drive technology. It is possible to select between AC and DC motors. The former have great durability while the latter produce less vibration and less noise while using power efficiently. The main horsepower options include 1/3, 1/2 and 3/4 horsepower. The motor unit can be equipped with one or two lights. These are turned on automatically when the opener is in use.
The motor units of the brand can be paired with a T rail or an I beam rail. The rails come in different lengths including 7, 8 and 10 feet.

This is typically necessary for garages that have been designed to house taller vehicles such as campervans.
