Pre-cut foundation to suit eight trifold frames from the Q8 Queen Mating Nuc.
The 24 panels are cut to suit the frame shapes and are pre-drilled at the top of each panel with two holes for the stainless steel screws. The bottom two screws go through the holes in the frame and thread into the plastic foundation. See photos.
You end up with a good quality frame that is robust.
The plastic foundation will need to be coated with molten beeswax before the bees will draw it out properly.
