We have very little experience in commercial doors. Thanks in advance for your advice. What would be the best way to replace this material? astragal seal as shown in pic

This looks a lot like our 58-091. Check it out and let me know if you agree. To replace it, simply unscrew the side channel, slide the old pile out, and slide the new in.
