This is a beautiful design that is incredibly lightweight, compact and versatile. It is much lighter than its competition because it uses 7075 alloy, the same super-strong aerospace aluminum alloy that Rock Exotica uses to make carabiners. 7075 costs much more than the more common 6061 that most rigplates are made of. But this allows Rock Exotica to make it nice and thin and save a lot of weight. Being thin also has the benefit of fitting carabiners and links better with less possibility of binding. Holes are numbered with laser marking.
