This 1-3/4" baluster is part of our Hampton Series.
These balusters have a graduating base block and a consistent turning area of 17-1/2".
The 5105 baluster is similar, yet has a fixed base block of 7-1/2" and graduating turning areas.
Look for matching Hampton Series pin top and ball top newel posts with 35xx (3" square) and 45xx (3.5" square) part number designations.
