Lets see some of the features this door offers that make it ideal for this area.

Section joints are roll-formed into a tongue-and-groove design which produces a superior weather seal.
Inside stiles are made of galvanized steel and stile holes are "dimpled" for increased holding power.
Extension or torsion springs are individually computer-calibrated to lift your door.
Extra-heavy paint system consists of .25 mil. primer with rust inhibitor and a .75 mil. coating of baked-on polyester paint.
Hinges are stamped from galvanized steel in a "wide body" pattern for greater stability and longer life.
