Came off a Rockwell saw that had no model number listed. Fits a cast iron top that is 22 deep when measured from front to back (not including the rails). See the photos for details. Condition is good, just one small cut on the end of the front rail as shown in the photos. The spacing on the factor drilled mounting holes was 11-1/2 apart on that saw in the front for that saw. I don’t have any other measurements to offer but that should be a good start and you can drill new holes as needed for mounting. Visit my online shop. For even more table saw parts!
