Constructed from durable 430 grade stainless steel, this sill cover offers excellent resistance to corrosion and long-term wear. With a 1/4" inside and outside width and a 6-foot length, it is designed to fit a wide range of smaller patio door track profiles.

Installation is quick and easy—simply remove the door, position the sill cover over the existing track, and reinstall the door. This makes it an ideal option for both professional repairs and DIY maintenance.

For best results on worn tracks, applying a small amount of silicone or lightly crimping the ends can help keep the cover securely in place.
