MYFAMIREA Garage Door Bottom Seals Rubber 16.4FT Weather Stripping Weatherproof Seal Replacement Strip Kit with 5/16"T Ends & 2 End Plugs, Universal U+O Ring Buffering Sealing for Double Track, Black

Great product but very difficult to install by sliding onto existing plastic rail. I did find a reasonable solution, I removed the rail and used a screen door roller modified with a washer to press into place, highly recommended method if difficulty comes up.

as long as the area to attach to is clear of dirt and pieces of old seal - it installed easy;

Nice flexible rubber, can be a pain installing as others have said. Make sure you order the right track style and thickness as your old one.

Works as designed

This door seal is a nice snug fit. It keeps the rain from seeping into our garage.
