Smartrope is an easy hanging solution for a hammock or a hanging chair for hanging from a tree, beam or post. You need two packets for a hammock and one packet for a hanging chair. It consists of a 3 meter long weatherproof rope, a carabiner hook and a metal plate that is so that you can adjust the length after you had hung the hammock up. It is easy to unclip the hammock to remove it when it is raining and just leave the ropes on the tree . Made by AMAZONAS.
