Basic Composite Adjustable Sill
- Continuous moisture- and insect-resistant all-composite substrate provides a solid stepping surface and superior rot-resistance.
- Thick moisture- and insect-resistant composite cap and nosing resists rot and features a wood-grained texture to complement home interiors.
- High-dam cap mates with the dual-bulb bottom sweep to help deflect moisture away from the cap.
- Zinc dichromate screws with removable screw caps resist corrosion and adjust to help maintain a tight seal over time.
- Thick, 15-gauge aluminum approach provides excellent durability and a solid stepping surface.
