PTH designed the RR-33 Riser Tool in 1984. It was throughly tested under strict criteria defined by the Hughes Engineering Test Department (test criteria available on request). The RR-33 proved to be the only tool to ever pass the test. Over 60 tools have shipped, representing a market share of over 80%, and most are still working today.

The HR-33 Riser Tool is now available from PTH. It is the same proven tool as the RR-33 but offers several important new features.
