Putting a short section of tubing on the string will protect the abrasion of the string by the frame. When you string those rackets also pay particular attention to the grommets in the throat they have a tendency to cause problems when the string cuts through them also.
EDIT: You could use nylon tubing it is lower priced but Teflon is more pliable. Don't make the tubing so long it protrudes past the inside edge of the frame but it must be long enough to bend around all points where the string contacts the frame.
