you could have used velcro and some tape to attach the velcro to the wall, then wrapped it around the edge of the rack to keep it in tight when pulling the stuff off the rack. thus keeping it all light weight and a whole lot less work. you can also adjust the height of the rack by shortening the legs by cutting them to the right length, or bending the length of the leg and then it won't destroy the surface of the bottom of the original cabinet. Just a suggestion for others to use your original idea. ;)
