4700 Series KD Sliding Patio Door

The 4700 KD Sliding Patio Door with Knockdown Frame offers a mid-range frame to glass ratio, a unique roller track system for effortless operation, blinds between the glass options, and a modular design with a patent-pending guide pin system for quick and easy alignment during installation.

“KD” indicates this door comes unassembled with a “Knockdown” frame ready to be assembled on-site. The 4700 Series KD Sliding Patio Door is easier to deliver to jobsites than pre-assembled doors, especially to jobsites with limited space or limited access due to known barriers.

White blinds and satin nickel or black hardware available as upgrades.
