exactly as advertised

I needed some custom-length spacers for my TPO-16 RC. Bought these 2-inchers, had a local machine shop cut them to custom lengths (and re-thread one end on each). That was far less expensive than buying tube stock and making them from scratch! Packaging and quality were excellent -- threads as purchased are nicely done, smooth, no burrs. Fine product.
