BLACK DIAMOND
Black Diamond Series by Sky Shark
We were getting a demand for tubes that had a better look and would help prevent bridle wear from friction on lower spreaders. So we brought back our original Black Diamond series tubes. They have a very hard clear-coat paint that makes them very smooth. The tubes are the same tubes as our standard 3PT’s, 5PT’s and 7PT’s. The only difference is we take grains, not grams of material off the tube very precisely. The amount of material in weight that is taken off is replaced by the weight of the paint.
