Elixir Industries Series 6000 Combination Doors are constructed from painted galvanized steel and attached to a high quality adjustable stop jamb. The weather stripping on both the jamb and the folded edge steel door core create a double seal protecting against light- air- and water penetration. Other features include a highly efficient polyurethane foam insulation with high R-Values- and adjustable stop- a drive-in swivel lock bolt- and a slopped threshold. The storm door comes with a built-in drip cap. Our storm door is 1-1/8" thick with a 1/8" tempered safety glass. Also- two additional options are available with the Series 6000 door: a closure kit and a chain. Other hardware items such as a deadbolt and a knocker viewer are also available upon request.
