When building the trellis some of pre-made holes weren’t lining up together to the point where you couldn’t get the bolt though without drilling a new hole. Also many bolts came mutilated so that you couldn’t insert a tool to tighten, they don’t give any extra bolts so I had to buy new. Before realizing any of this I had tried to return the item but the company never “reviewed my request” after weeks. So know if you buy this, you are stuck with it.
