For sale is a 6 foot long by 6 foot high heavy duty steel sheving unit. It ihas 4 shelves built into it. It is made from angle steel and is welded together. It rolls on 6" solid steel wheels, and also has a little hitch on the front to make it easier to move should the need arise. This is capable of holding a great deal of weight. This thing had about 3000lbs. sitting on it for about 10 years running. I had 3 short blocks and 1 bare block on the bottom shelf alone, 3 automatic transmissions, about 20 cylinder heads, and numerous heavy boxes and other parts, crankshafts, about a dozen generators and starters, etc. at the same time for a long time. All 4 shelves were completely full at all times. I'm retired and no longer need this, Comes complete with wood installed just like I have been using it all these years, Ready to go. Good unit if you can use it. Item is located in the Bridgeport neighborhood on the s/w side of Chicago. Thank you.
