Product Specifications

Features and Advantages

• 🔪 Freely adjustable size Unique tear‑apart design allows users to easily split the 9mm-wide strip into two or more segments according to the actual width of the door gap, eliminating the hassle of purchasing multiple sizes and enabling versatile, multi‑purpose use.
• 🛡️ Powerful Sealing Protection Effectively blocks cold outdoor air, dust, noise, and small insects from entering the home, keeping the indoor environment clean and quiet while enhancing the energy efficiency of air conditioners and heaters, thereby saving energy and reducing electricity consumption.
• 💪 Excellent rebound performance Made from high‑elasticity silicone/EPDM material, it remains deformation‑free after tens of thousands of door opening and closing cycles and can quickly return to its original shape even after prolonged compression, ensuring long‑lasting sealing performance.
• 🧩 Easy and hassle-free installation It comes with high‑strength adhesive—simply clean the surface of the door frame, peel off the release liner, and stick it in place. No nails or glue are required, making installation a breeze even for women.
• 🌿 Eco‑friendly and durable materials : Odorless and non-irritating, it is resistant to high and low temperatures and aging, and remains flexible, crack-free, and non‑delaminating even after prolonged use.

Installation Steps

1. Clean the surface Thoroughly clean the areas on the door frame where adhesive will be applied using alcohol or a cleaning agent, ensuring they are dry, free of oil and grease, and free of dust.
2. Measurement and Cutting Measure the length of the door gap and cut the seal to the appropriate length; if the door gap is less than 9 mm, tear along the pre‑marked dashed line to adjust the width.
3. Peel off the adhesive backing. Remove the release liner from the back of the sealing strip.
4. Paste and secure Start from the top of the door frame, peeling and applying as you go, pressing firmly to ensure a tight fit—pay special attention to thoroughly pressing down at the corners.
5. Inspect and repair After installation, test the door’s opening and closing. Trim any excess parts neatly if necessary.
