Propolis Trap [511]

15 5/8"(w) X 19 5/8" (l). 

Put this trap on in place of your 10-frame inner cover.  The side with the lip around the parameter is placed downward; the smooth parameter is oriented up toward the top cover.

To harvest propolis, put the trap in a bag and put it in the freezer for a day. Take out and bang on your counter and propolis will fall from the trap to the bag. You may also flex the trap to release the propolis as well.
