Notes:
  1. We offer knobs with screws having either 30 mm or 35 mm length. Order knobs with a screw length sufficient to allow the knobs to clear the secondary housing. Knobs with 30 mm screws are the most common in this configuration. However, the 12 , 14 , and 16 sometimes require knobs with 35 mm screw length.
