Use these Accu-Dots with the Hu-Friedy Accu-Placer. Order by the dozen.
You can also use Accu-Dot to stick the chain to the side of your placement instrument so that it stays up and out of the way during the procedure.
Keep those pesky chains from getting sucked up or dragging you down with their extra weight while you are placing the pad. Beware: Addictive!
