Measuring ballet Barre Warp Tolerance diagram

Step 1: Sight down barre to determine apex of the warp.

Step 2: Center the 4’ level on the apex and secure the level to the barre (using tape, tie, etc) as shown in the diagram.

Step 3: Attempt to slide the 3/16” drill bit into the gap.

Step 4: If the drill bit slides freely and completely through the gap, then the barre is beyond our warp tolerance. Immediately call Alvas for return instructions.
