Premium materials and design

Crafted from fluoroelastomer, this weatherstrip offers robust wear and high-temperature resistance, with the material quickly returning to shape after compression. Its adhesive qualities further enhance sealing performance, helping to form a reliable barrier at each seam.

Upgraded design emphasizes a wider and deeper seal that makes good contact with Bilco thresholds, accommodating slightly aged or bent doors while extending overall length for long-term sealing. The kit's extended lengths help maintain coverage even if alignment shifts slightly over time.

Easy installation and support

The kit is designed for quick, DIY-friendly installation with no special tools required beyond tin snips or large scissors. A typical installation takes around 10 minutes. For visual guidance, you can check the available installation videos.

• Tools required: tin snips or large scissors
• Estimated install time: about 10 minutes
