Listed below this section details what each type of mount configuration offers.

  • Provides 23" your tube swing-through room. Compute your swing-through distance here or e-mail for help.
  • Front, side and bottom boards connected rigidly, braced by internal 3/8" dowels, and screwed together.
  • Altitude bearings have inside tube braces cut to match tube curve.
  • Altitude bearing tube mounting requires two 3/8" bolt holes.
