The frame mounting rollers on my tradesman table saw have finally worn out over decades of use. I removed the original Sears Craftsman wheel assembly and replaced it with this wheel set. What a difference moving a table saw from one place to another makes! Parking brakes are ideal for stabilizing a table saw. I had to attach the original stamped sheet metal legs with a 1" corner. I gained about 4 inches in height thanks to these rollers. I am very happy with this reel set.
