These tubes should be 22.125 inches. Only two out of 8 are close enough to this length to be usable. The remainder will be extended between 22.125 and 22.25. Each one seems to be a different exact size, but six out of eight don't fit my jigs. Of course, the product return window is closed and I lost about $30. I strongly encourage you to find another product with more reviews. Quality control is not a problem for this manufacturer.
