English to Spanish Tech/Engineering Architecture installation of fiber glass columns

All round fiberglass columns used with decorative capitals should be trimmed flush above the bead/astragal. The capital should rest on top of the bead/astragal and will allow for a proper fit. Columns can be ordered from the factory cut at the
bead, or this can be trimmed in the field. A circular saw with an abrasive blade can be used to trim a column at the bead/astragal.
There are several considerations to be made when ordering fiberglass columns used with decorative capitals. The cut at **bead loss** and the decorative capital height must always be taken into consideration.

Any idea? Thanks!!!!!
