The Eagle Band Hook from ermes sub holds tension on the second band's wishbone of a double roller gun set up. It goes positioned underneath the barrel of the speargun towards the handle, behind the single eagle band hook creating a loop point that holds tension on the band that is wide enough not to interfere with the first band while the speargun is loaded.
Its three-piece design makes it both simple and effective. It has a base that lies flat against the speargun, a thicker middle piece that fits the wishbone line precisely and a top part with a hook that keeps the line from coming out. The unit is 58mm wide.
