NOTE – the last four of the part number (aka “2004”) I believe is the year manufacturered… I have seen 2003, 2004, and 2006 printed as those last 4 digits. They all fit the same guide rail, just slightly different color/finish. Includes ONLY the part shown… If you need a full assembly, v. For even more table saw parts! Fits a Unisaw Fence that is. 3.4 inches wide. 1-3/4 tall on the front/narrow end. About 2 tall on the back/wider end.
