Surface Mounted Automatic Door Bottom, Door Draft Stoppers, Auto Threshold. Customizable Length, Peel-and-Stick, Tool-Free Installation, Works with Wood, Glass or Metal Doors (Silver, Left)

Step-by-Step Installation Guide 1. Test Fit & Trim (If Needed) Close the door with the seal temporarily positioned to check length. If too long: a. Remove the rubber seal strip. b. Cut the aluminum housing (on the non-striker side) using a hacksaw/grinder—avoid damaging internal components. c. Reinsert the seal and trim the rubber with scissors to match the door frame distance. 2. Install End Caps Attach the included black end caps to both sides of the seal. 3. Partial Adhesive Application Wipe the contact surface clean and keep it dry. Peel back 2 inches of the red backing film from both ends. With the door open: a. Align the seal’s bent edge with the door bottom. b. Center the seal and press the exposed adhesive ends lightly. Pro Tip: Leaving most film intact allows repositioning before final commitment. 4. Install the striker plate Close the door to locate where the striker pin contacts the frame. Mount the striker plate at this position. A adhesive-backed metal plate or plastic block with screw holes. 5. Final Adjustments Remove all remaining red backing film and press the seal firmly for full adhesion. Adjust the striker plate’s depth until the seal makes snug floor contact when closed. FAQ : 1. Why does the seal not extend evenly? During installation, you might press the striker pin by hand and notice that only one side of the seal extends while the other doesn’t—don’t worry! Press the extended side—the other will follow. It’ll seal perfectly when the door closes! 2. Why is the seal strip longer than the outer casing? The seal strip is cut to match the width between door frames, ensuring full-width sealing. The aluminum casing is slightly shorter to allow space for the striker pin movement and adjustments. Additionally, the casing being narrower than the door prevents unnecessary scraping. 3. Can the Automatic Door Bottom be removed? Yes. Since it uses peel-and-stick adhesive, applying heat (e.g., with a hairdryer) will make the seal strip easier to peel off. If adhesive residue remains, you can wipe it away with a glue remover solvent or use a physical cleaning method. After removal, your door will remain undamaged—no screw holes or marks—and the seal strip can be reused on another door.
