Akro-Mils announces the expansion of its Super-Size AkroBin line of large plastic storage bins with a new mobile kit for bin models 30288, 30289, 30290, 30292, and 30293. The three-inch locking casters are quickly attached to bins with the included hardware pack for easy mobilization. Molded of industrial-grade polymers, the bins are resistant to weak acids and alkalis. Super-Size AkroBins' reinforced side ribs add strength so the bins maintain their shape when stacked. The bins are available in 12 different sizes and four colors: red, blue, yellow, and clear.
