MD Casting was founded in 1982 and originally manufactured body side molding tips for the automotive aftermarket. In 1985 the company began its migration into the fenestration industry by introducing a line of window locking mechanisms. Today, its product portfolio consists of multiple styles of cam locks and keepers for all types of windows, tilt-latches, secondary latches, as well as a complete line of pivot bars.

Through these specialized product lines, MD Casting furnish key components on Atrium windows produced throughout the company’s family of fabrication facilities. In its quest to be as vertically integrated as possible in its supply/value chain, Atrium is able to control the quality, consistency and availability of the component parts sourced through MD Casting.
