The Marvin Signature™ Ultimate Sliding French Door offers the elegance and upscale look of a traditional French door with a space-saving sliding design. Engineered for both quality and performance, this door is available in varied configurations as single, double, triple or quad panels. The door offers beautiful, substantial wood surrounds with nearly effortless operation and a durable sill for weather protection even in harsh climates. If accessibility is important, choose an optional low-profile, performance-rated sill for a smooth transition threshold between interior and exterior living spaces. If the view is the focal point, enjoy sizes up to 16 feet wide with openings approaching 7 feet for a strong connection to the outdoors.
