The Capital with Block is the top trim part of the modular column. Also available separately, are the turned ring portion of this part (capital), and a cap (abacus). This gives you two ways to terminate the column at the top.
Make sure you order the Capital size that matches the diameter of your column shaft.
For use as onlay moulding, order the parts split to fit flush on the surface of your cabinet, wall, face frame or door casing.
For corner applications, order the parts notched.
