Description
StringBlok® is the original and patented offset stringing block designed and hand-crafted by Jupiter Strings in Florida.
U.S. Patent # 7,765,880.
This tool eliminates string damage at the tie-off point by keeping the string away from the frame while you knot. No crushed mains, no crimping, no premature breakage. StringBlok® has been tested on thousands of rackets with zero customer breaks at the starting knot.
Built from premium Sapele hardwood and shaped to fit every racket head and beam profile, StringBlok® gives you consistent, clean tie-offs and professional-grade stringing results every time.
Whether you are a pro stringer or a player who demands better workmanship, StringBlok® guarantees a 100 percent clean, damage-free tie-off on every job.
