Accessories for the edge sanders. The positioning aid holds the machine at the angle you set so it doesn't drift over a long edge. Base runners come in hard and soft: hard where the edge is straight and you want it kept that way, soft where the edge curves. Slideway linings are consumable — they are what actually contacts the workpiece, and once worn the machine starts marking the surface it is riding on.
