Perfect straightness is difficult to obtain in a natural product like wood

Measuring ballet Barre Warp Tolerance diagram
  1. Sight down uninstalled barre to determine the apex of the warp.
  2. Center the 4’ level on the apex and secure the level to the barre (using tape, tie, etc) as shown in the diagram, then lay barre with a straight edge on the floor.
  3. Attempt to slide the 3/16” drill bit into the gap.
  4. If the drill bit slides freely and completely through the gap, then the barre is beyond our warp tolerance. Take a close up photo of the full 4′ area and a photo of the entire barre with the straight edge (like diagram above). Immediately call Alvas for return instructions.
