Redoing our garage and decided to put in new shelving. Did some research and found these Gladiator steel shelves. Wow, what a find. I am a 56 year old woman and put these shelves together with no problem whatsoever. The design is genius, requiring no tools. Didn't even have to look at the instructions, it was so easy. They just easily snap in place and are extremely durable and strong. They make a beautiful finished product. The best thing is, if we move we can easily disassemble them and take them with us...which we will. Extremely happy with this product!!!!
