Next I used suction cups to move the glass. You want to pump them up until you don't see a red line. If you see red, you're dead. This is half inch thick tempered glass and it's pretty heavy. Once the glass was in place, I attached the hardware. It has rubber pads inside to protect the glass and keep it from moving. There's two allen head screws that draw the clamp together. This bottom piece was the hardest. With all the angles and multiple brackets, I had to use shims to get everything to line up. I've never worked with the glass before,
