Easier to put together than you think once the small box arrives. This snaps together so it is very secure and pieces won’t blow apart through a storm. My husband and I put it together in under 30 minutes. There is a point that 2 people are helpful but not needed. I accidentally handled him pieces out of order and after they snap together that’s it. So we did the same on the second one and you can’t notice. Good quality trellis and it covers our hvac unit perfectly.
