Thanks for reaching out! You may be able to replace your bottom door sweep using our High Performance Door Bottom. Although, to confirm that this is the right fit, you'll need to carefully compare the dimensions for the space between the kerf at the top of the door bottom.
This High Performance Door Bottom is available in a 36" length and a 48.25" length.
Unfortunately, this is the closest match we have to your door bottom. If you have compared the dimensions as shown on the diagram above and they are not a match, I'm afraid we do not have a replacement that will work for you. You can view our selection of bottom door sweeps here.
Our sincerest apologies we couldn't be of more help.
Have a great day!
