The name is a bit misleading - while the Clamp gets its namesake from the resemblance it has to a Spruce Tree, the entire clamp is made out of Poplar. Why Poplar? Well, the three attributes that were essential to this project were price, quality, and strength. In this case, Poplar is the best choice. Also, it goes without saying that we strive to have the least environmental impact, which is why the Poplar dowels used are grown and manufactured in the USA. The annual growth of the forest exceeds the harvest, which of course is a good thing.
