Front door threshold metal gap thingy
MY front door threshold is metal and has a kind of lip/groove that locks into a corresponding metal tongue that is on the bottom of the door. The piece on the door has gotten a bit bent and after I 'fixed' it, is all mangled. What is a real fix for this? I went to big box to get another piece for the door but they dont have it. I am not opposed to removing the piece on the door but what to replace it with? This door is about 20 years old.
