I'm disabled so I had a contractor laydown laminated flooring
in my kitchen - three years ago. He put in a 2" metal threshold
between the floor and the carpeting.

The problem is that the laminate is starting to chip. When I
removed the threshold, I saw the cause of the problem. The
contractor failed to cut under the door frame and the threshold
does not extend far enough to get a good grip on the laminate.
...

Thanks to advice I got here I bought bought a Jamb Saw and it
worked great.

Problem remains that I have yet to find a 2-1/2 threshold.
They all seem to be either 2" or 3".

I've checked with Home Depot, Lowes, and every laminate
and/or carpet store I found online or in the yellow pages
within 50 miles of me.

Any ideas?
