Door sweep with 4 bulbs to seal 1/8" gap

I'm afraid I can't tell what sweep you have from this photo. How does it install? Does it use kerfs or staples? If it uses kerfs, we'll need you to remove it and tell me the distance between them. To get an idea of how sweeps like this can be designed, you can see our entire selection here. 

You may want to just go with the 58-176. This works on most doors because it just wraps around the bottom and installs on the sides using screws.
