Ultimate Cliffhanger 8 inch Boom Stick

  • 8 Inches long
  • 1 1/2" Deep.
  • Fasten with 1 bolt and two screws, or with (4) 3" long Screws.
  • Boom Sticks were designed to allow customers to create a much more challenging version of the "Ultimate Cliffhanger" obstacle as seen on the American Ninja Warrior T.V. Show.
  • The primary rung used on the show is 2 1/4" which allows most people to get the full length of their fingers onto the rungs. These Boom Sticks will only allow you to grab up to your second knuckle.

  • These guys have a slightly rounded edge, and a more rounded edge. The round edges will make these rungs a little more difficult to hang on to, but they'll allow you to train longer and harder without damaging your skin.
  • Our original 24" long Boom Sticks had 90 grit texture. These new 12 inchers have very fine 200 grit texture. Your skin will thank you :)
  • Made with pure polyurethane.
  • Designed by Steve Dison.
  • Released 2016/06/21.
