I'm sure this throat plate is fine for the correct saw, but Amazon has poor lableing. I had to return it. Listing it as the insert for 'Delta Contractors Saws' is an error. It fits right-tilt contractors saws, not left tilt. The left-tilt contractors saw throat plate is listed as the one for left-tilt Delta Unisaw, but is the right item for their left tilt contractors saw as well.
