Specifies the actual outside diameter of the pipe (or insulation). By default, it is set to some reasonable value. Typically this value is passed in by the Assembly Information Rule (AIR). This value is used to position the strap vertically along with StrapTopGap.
IJOAhsPipeToSteel::PipeToSteel
Specifies the clearance between the outside of the pipe and the steel. By default, it is set to some reasonable value. Typically this value is passed in by the AIR.
IJOAhsSteelThickness::SteelThickness
Specifies the thickness of the steel to which the U-Bolt is attached. By default, it is set to some reasonable value. Typically this value is passed in by the AIR.
IJOAhsRoty::RotY
