[Woodworkers] Different saw

[Tom Lovelace]

Just watched a video on Youtube and A very different method of making minor adjustments of the tablesaw fence.
Anyone ever ran across an item like this? It sees to be a one inch threaded rod that goes across the front edge of the saw.
The operator just turns a  knob located at the left end of the rod to make minor adjustments. See the two picts:  Sure looks shop-made?
