THESE ARE VERSITLE! A set of 6 interlocking HEAVY DUTY commercial black steel grid cubes. They measure 12” x 12” x 14” and have a 1 ½” foot. I have used them from storing books, to holding my 36” TV, a few stacked in my closet for sweaters, etc., in the pantry, a have two I’m using as a coffee table (just threw a granite slab on top). They lock together securely, yet are easily to take apart if you want to rearrange them. Use your imagination! kansas
