Threshold Extender (10" to 36" Width)

It fit perfectly, no issues, fairly rapid shipping too.

I needed a specific size extender for a new exterior door. I was unable to locate anywhere until I found it here. I was hesitant I would somehow screw up the measurements since it had to be special cut but it ended up fitting perfectly. Guy installing said it just snaps into place. Glad I found this place

Came in a timely manner and was exactly what I needed.
