4" Black 1/4" T-style Heavy Duty Rubber Bottom Garage Door Seal (priced per pre-cut length.)

Are you looking for a replacement seal for the bottom of your garage door? We offer the 4" wide black rubber heavy duty bottom seal that is compatible with Raynor garage doors, Gadco garage doors and other brands of residential & commercial garage doors that have bottom door retainers that accept the 1/4" T-style of seal. The underside of the bottom seal is ribbed to help keep the dirt and water out of your garage.

The seal measures 4" wide when layed flat. The 4" Heavy Duty Black Rubber garage door seal works best for garage floors that are uneven. The wider bottom weather stripping helps to fill in gaps between the bottom garage door section and the garage floor. If your garage floor is in good shape and level then use the 3" Black Heavy Duty Rubber Seal.

  • 4" width black heavy duty rubber bottom garage door seal
  • Seal slides into bottom garage door section astragal retainer
  • Priced per pre-cut lengths of 8', 9', 10', 11', 12', 13', 14', 15', 16', 17', 18', 19', 20', 22', 24', 28', 32' and 40'
  • All seals are cut 5" to 6" longer (at no extra charge) so you'll have extra seal on each end to tuck back into the retainer
  • Fits GADCO and Raynor brand doors that use a true 1/4" "T"
  • Note: due to tolerances in manufacturing the actual width of the seal can vary from 3.775" to 4"

Compatible with the following Raynor models: Aspen Series (AP200LV, AP200, AP138), Tradition Series (Masterpiece, ShowCase), Advantage Series (TradeMark, BuildMark), Discontinued Models (Classic, Decade I & II, Affina, Centura, Relante, Prisma, Charleston); Commercial Models: TC Series (TC320, TC300, TC200), ThermaSeal Series (THM220, TM200, TM175), SteelForm Series (S16, S20, S24, S24-C), Discontinued Models (Tri-Core, Styleform Standard & Basic)

  • If you need seal for a Clopay, CHI, Ankmar, Amarr or other brand then you should get a seal with a 5/16" "T" (some seals are called 1/4" but are actually 5/16"). You can use the 4" Black 5/16" T-style Rubber Seal.


  • Installation tip: have two people to install - one to pull the seal through the retainer and the other to feed the seal into the retainer. It's also a good idea to put some soapy water or lubricant on the retainer before trying to pull the vinyl seal through.
