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

Replace the worn out or torn bottom garage door weather seal on your garage door with heavy duty rubber replacement bottom garage door seal. The 3" wide rubber bottom door seal works in Raynor garage doors, GADCO garage doors, and other residential & commercial garage doors that have retainers that accept a 1/4" T-style bottom garage door weather seal.

If you have an uneven garage floor with gaps between the bottom section and the garage floor you may want to consider using the 4" wide bottom garage door seal. If you have a good level garage floor then use this 3" seal which is more commonly used.

  • 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.
