The PT-5700-00 is a great option to upgrade the nut on your seven string Strat or Tele style guitar. It has a radiused bottom and is 7/32" tall. It is pre-slotted for a quick and simple install. Note: All Graph Tech nuts and saddles are slightly long and wide to ensure extra room to achieve a perfect fit for your guitar. This extra material can easily be removed with fine grit sandpaper.
