The Contemporary Collection Sliding Patio Door is designed to be controlled with a single lever that shifts the active door panel inward, perpendicular to the wall. The shift releases the perimeter sealing gaskets so the door can slide with little friction. When the door is in locked position, the panel is drawn to create a tight seal with multiple lock points on both stiles. The 1 ¼-inch low-profile sill is designed to divert water away from the interior. An optional direct-glazed version of the door is available.
