PlayStar's Ninja Power 3-in-1 Play Line PS 5000 can be used alone as a slack line, hung overhead as a training line, or as a ninja line by adding grips! When the 60-foot-long high-tension play line is attached to the Ninja Power Tower or Ninja Platform Kit, it will quickly transform your backyard into your child's very own ninja course. Enhance the excitement by purchasing our Ninja Grips which easily attach to the play line to challenge your children's strength and creativity as they make their way across. The PS 5000 includes a ratchet strap and weatherproof sleeve for covering the ratchet. Ninja Play Line Anchor PS 5010 is sold separately. Thoroughly tested for safety and comes with a 10-year warranty.
