This thin nylon cord is incredibly strong, but almost invisible when attached to one of the poster rods. The Metal picture hook has a adjustable wheel attached to it so that when the cord is passed through the back of the hook, it can be clamped into place, by screwing in the wheel. The loop at the top of the cord is permament and fastened with a metal ring and then the hanging height of the poster can be easily adjusted in length at any stage. This one is designed for the groove of the rods.
