A great multi position tool post by Enco. Nut fits 1/4 thick compound slot. Overall nut thickness is 1. Nut length is 3 9/16. As my retirement hobby I've restored numerous South Bend lathes to showroom condition.
Over the years I've collected quite a backlog of parts. The items I post are clean but will have some dings, dents, and blemishes from normal use and age. I try to take pictures from all angles to point out areas of possible concern.
