These 120mm caps fit all three styles of SuperGourd (i.e., the 2-1/8 round, 1-3/16 crescent, and 1-1/2 bluebird entrance holes).  Caps are impregnated with UV inhibitors for long life and new heavy duty mold with ribbed grips all around the edges.  They have a white cardboard liner to block incoming light.  These caps are the perfect replacement for lost or broken caps.   Note:  Shipping is free when purchased with SuperGourds or Pole Systems.
