The Short Olympic Weight Plate Holders from Titan Fitness are the perfect solution to storing your change plates. The 5" long sleeve length means less room needed for the holder but still enough room to fit several plates.  These holders fit on every surface of your X-2 Series Power Rack and only fit the sides of your T-3 Series uprights. If you want to place this on the back of your T-3 Series rack please see the X-3 compatible listing.
