Garage Door Bottom Bulb Style Weatherseal for Windsor Doors that use this type of seal. 

This weather seal is approx. 4" wide when laying open. The bulb measures approx. 3/8" in diameter. 

Please check the type of seal that your Windsor door has. Please don't assume that just because your door is a Windsor door that this seal will work!

Bought on ebay and reselling as it did not work for me
