I started with the standard 99.75″ main leg and the parts list for that section reads an estimated price of $261.30 (or $458.83 for the entire bar)
Once the main leg is resized to 60″, that section is now $215.95 (or $418.95 for the entire bar)
So, what part do you see that increased?
Be sure you are NOT using the MATCH function….and if you are using the match function, you need to read the user guide.

Keep in mind those prices are estimates only…and probably on the high side, and includes solid oak arm rest boards.
