Standard Ball Drop Sub

Blackhawk’s 6-5/8” Wiper Ball and Dart Drop Sub allows Nerf and rubber wiper balls and darts to be pre-loaded into an enlarged-ID handling sub and made up to the drill pipe for quick deployment into the landing string after completion of cementing operations.

    Features

  • 6-5/8” FH connections with large 5.50” ID makes loading foam and rubber balls
  • Reduces risk of loading balls or darts into drill pipe over the rotary and darts easier, while maintaining API connection ratings.
  • Can be run above HD Top Drive Swivel to launch balls or darts when flow around capability is not required.
