You need this! - Jerry
Do yourself a favor and do not order the GDR60 without the GDRT6. This thing is heavy (good thing) and sturdy. Make sure you have a 10MM Allen key to mount as they do not provide one in the packing. Ask for Terry L when placing an order. He will take good care of you.
Very Solid -
Like the other reviewer said on this: this piece is a MUST have along with the main dumbbell rack. IF you don't get this piece at the same time, you will have to loosen up the other two tier's. Kind of a pain, so get this along with the main rack and you avoid the above. Mine is almost loaded with 5 lbs through 60's, then a pair of 75's & 95's. It is SOLID, indeed. I have a couple spaces left. Like most of Body-Solid's gear: VERY good value for the money. Dave at the Aurora store has been excellent with his customer service and prices!
