I was first stressed out due to other reveiws. When received this i read the instructions a couple of times and put this together myself, with in a couple hrs. I placed both glass panels in the shower so i could move them when needed to install. The key to take good measurements. I bought the 72” wide kit and the glass is very heavy, so it would be smart to have a friend help. The glass is 3/8” thick. Its not gonna break when you put your hand on it as one other review indicated. Th make this glass break you would have to hit the corners on something solid or hit it with something. Any way this is a great purchase and the price was great. Glass company’s price are rediculus. I checked with several companies before deciding to buy an instal my own saving thousands most quotes i got were 2500 to 3500 for glass and insulation. Pay attention and read the instructions, its not brain surgery. Good luck.
