This is a rip fence from a vintage Delta/Rockwell unisaw. It fits saws with a 27inch deep table and 1 3/8 inch mounting tubes. The fence is missing (1) a bolt that screws into the top of the fence and (2) the knob that goes on to the end of the fine adjustment gear. The fence is operational without these, but I’ll mention them so you know what you would need for the complete the set up. Also, I noticed a slight bend in the shaft of the locking arm. Again, no interference with operation of the fence, but I’m just mentioning it. Please take a good look at the photos and feel free to ask any questions that you may have.
