has delivered the plastic caps that hold the hammock were broken! but the installation of the hammock so still possible I considered that I did not refer the article and could use it as well! But unfortunately a few days after being installed the hammock! I found the foot of the gallows disconnected hammock! pieces (necklaces) supporting the structure were torn! I had to re-drill the structure and bolted to find the desired function on this product! especially do not buy this product if you do not want to tinker behind! and the attention of the designer of this structure -> it's review !!
