Support your crimp wired foundation without wire. Insert these split pins into the eyelet holes on the endbars of your wooden frames. The wax slides right through the split into the metal to secure the wax to the frame prior to the build up of foundation by your honeybees. Use 4 pins for medium or shallow frames and 8 pins for the deep frames you'll be extracting.
1000 pins is enough for about 250 medium or shallow frames or 125 deep frames.
