I just finished assembling the Gladiator Heavy Duty Mega Rack in my garage without the use of any tools and it only took me about 15 minutes. This shelf is built commercial quality. It’s rated to hold 2,000 pounds per shelf and 8,000 pounds total weight capacity and I have every confidence that it would. The shelving heights are fully adjustable and you can buy additional Mega Racks and connect them making longer units. I’m impressed with the quality of this product and highly recommend it.
