One of the blocks has threaded holes for the thumb screws. The aluminum block has countless configurations, such as with a U-bolt clamp for installs with tight clearances, with longer bolts for wide reaches, or simply bolt one half to a flat surface. This clamp base is compatible with all Rock Steady mounts.
