}

This property lets you determine how close to the structure’s rim you can position a pipe. It is used for two-tiered junction structures only and specifies the clearance required above the top of the barrel section of the structure. It is similar to Vertical Pipe Clearance, but only describes the transition zone between the access cylinder and the larger barrel cylinder of a two-tiered structure.
