Each Bell by itself holds 50 seeds. I have included a EMT clip in the file that you can bolt to the bell and clip onto EMT or there are slots that you can ziptie onto another surface. If you want 2 bells like in the picture I have included the right, left and top connectors that EMT pipe will go ( the side EMT pip will be 12 1/2 inches long (2 of them) and the bottom will be 13 inches long (1 on them) If you use the the EMT clip it uses a #6-32x1/2 bolt (Lowes item # 35195
