Ninja/Parkour spinning hand obstacle device.


Spinning Door Knob Features:

  • Made with sealed bearings 
  • "No hardware" means you are buying the knob plus a pair of sealed bearings. 
  • A schematic drawing is posted in the photo thumbnail section of what the hardware kit does and how it should be set up.
  • Discounts do not apply to this product.
  • This product has a 3% wobble tolerance, meaning we test each hold for balance, but it's not a perfect world. 
  • The backer plate is wood, not a metal plate.
