Supplied brackets worked perfectly on my Bridgeport. There is a small amount of side-to-side play in the slides, which is needed. The sliders have hex shaped indentations which work very well for nuts, and the holes are threaded. There is not a single extra nut or bolt, and in modifying the mounts I had to pick up some extra metric screws. The long armored cables and plastic readout cover will ensure long life in the shop environment. I've had some trouble with the instructions, particularly the "half" command and in setting the + vs - direction of movement, but otherwise a very good purchase so far. Low-price, good-quality products like this are why the Chinese are eating our lunch.
