This draw plate is laser cut from acrylic and specially designed to minimize marring wire as you draw it down. Start with a length of knitted or braided wire rope, then draw it through successively smaller holes until it is the size you need. Each hole is slightly tapered to make a smoother and more even draw. The plate has two sets of holes, one marked with millimeters from 16 mm to 3 mm and the other inches and 5/8 in to 1/8 in. 22 holes total.
