I was hoping to locate a steel company or whoever to purchase the rug grids for dusting rugs. Does anybody know where to find them or what is the proper name for them. I know I can get them from Rugbadger and Centrum-Force, but I was hoping to find them else where (cheaper). Unless they are having these custom made, it looks like something that would be easy to buy "over the counter" if I could just figure out what is is called and where to buy, anyone?
