This model can hold up to 24 shellholders. You can stack two shellholders on the same pole, or just use one shellholder for a total of 12. The poles is just inserted into the holes by hand. To remove the support, use a wallpaper knife and set the blade in the center of the support and flipp it. The square is just 100x100 mm in size, so it will not take a lot of space on your reloading bench.
