Endura Aluminum Z-Series Adjustable Inswing Cap Sill

Z-Series Door Sills are simply the best sills on the market. The Z-Series uses a patented design of all synthetic components that eliminates the worries of wood substrate sills. The Endura Z-Series family of sills provides modularity within components, allowing you to upgrade your system as your needs change.

Built to last, the advanced all-composite substrate and streamlined aluminum cap means no rotting, warping or deterioration over time, perfect for high heat climates. Patented screw covers keep debris out for easy adjustment anytime and prevent exposure to unsightly rusted screws. In addition, the cap seals overlaps the dam to protect the channel from debris.

*While we know it’s fun to door-it-yourself, we recommend hiring a professional to replace your sill system. This product is recommended for uninstalled doors and professional use only.
