The accessory that gives width settings for the rip fence on a table saw is the Fence scale (Option D). A fence scale is a measuring guide attached to the rip fence to help woodworkers set the exact width of a cut for ripping boards. This accessory ensures precision and repeatability when making cuts at various widths.
The miter gauge (Option A) is used to guide the workpiece at a set angle relative to the blade for making crosscuts. A dado blade (Option B) is a specialized blade used to cut wide, flat-bottomed grooves in a workpiece. And a featherboard (Option C) is a safety accessory that holds the workpiece firmly against the fence or table surface to prevent kickback..
