Tapered column wraps ship as two L-shapes that fit together around a structural post (4x4, 6x6, etc.)
Craftsman style cap & base trim included but ship un-attached. Their use is optional at installers discretion. Other C&B styles are available. Shaft width dimension is listed. C&B trim adds to that "footprint".
Tapered column wraps can be cut to adjust for height. Always cut from the bottom.
