The Wayne Dalton Bead Bottom Seal 4 is a replacement garage door bottom weather seal designed for sectional doors that use a Wayne Dalton bead‑style bottom retainer. Its beaded edges slide into the dual channels of the retainer to create a continuous barrier along the floor, helping block drafts, water, dust, and pests while cushioning the door on close. This bead‑end design is intended for Wayne Dalton residential and light commercial doors equipped with the matching bead retainer and is not compatible with T‑end, P‑bulb, or single‑track tongue retainers. For best results, confirm your existing bottom retainer has two parallel channels that accept bead ends before ordering or installing.
Installation is straightforward: with the door fully closed and the opener disconnected, remove end caps or fasteners from the bottom retainer, slide out the old strip, clean the channels, then use a mild soapy‑water solution to feed both beads into the tracks and slide the seal across the full width of the door. Center the seal, trim any excess, and reinstall the end caps. Avoid petroleum‑based lubricants during installation. Basic safety practices apply—work with the door down, keep hands clear of pinch points, and ensure the door is stable. This Wayne Dalton bead‑end bottom seal is an ideal replacement part for restoring a tight floor contact on compatible garage doors, improving comfort and helping reduce debris and moisture intrusion.
