I received my 90" x 90" Heavy Duty Mega Rack on 29 October. Although I was extremely anxious I had to wait a few days for  assembly. I had to find the right space. Remember, this is a MEGA RACK. It took a few days to complete that. After completion it was assembly time. I unpacked the box and separated all the parts. Assembly was a snap. This job is for two people but can be done alone. It took me 45 minutes to complete. I am going to be using the rack to put multiple aquariums on. So, that 2000 pounds wait limit per shelf will be thoroughly tested. Water is 8.34 pounds per gallon. All in all, the Mega Rack is an attractive and sturdy addition to my garage.
