Zusammenfassung:Systems, apparatus and methods useful for increasing the outer diameter of a tool string at a desired location in the tool string involve a spacer tool having a mandrel releasably engageable with at least one other tool of the tool string and a gauge ring distinct from and releasably, non-threadably engageable with the mandrel. The gauge ring extends radially outwardly from the mandrel to provide the spacer tool with a maximum outer diameter that is greater than the maximum outer diameter of at least one other tool in the tool string.
