The listing

Store and unload heavy, bulky items with convenient four-way access to shelves. Quick, easy assembly. Shelves snap into place and adjust at 1 1/2" increments. 3 shelves hold up to 1,500 lbs. each. Smooth, solid 5/8" particle board eliminates item fall-through. 48 x 48 x 81" I trimmed a few inches off the top support beams to allow it to roll under my garage door rails.
