Sliding door assembly
View Patent ↗The frame and the sash of the sliding door assembly are each made of plastic. The frame extrusion profile utilizes an opposing open-leg or C-channel construction that creates an interior accessory slot that is utilized throughout the overall construction to create a carrier that can accept a wide variety of snap-in accessory extrusions or components. Similarly, the sash extrusion profile allows for the use of snap-in accessories.
