Window Sills, Jambs and Headstone
This type window trim often used in school and industrial buildings is shown with a through sill. The inside face of this sill is finished and may be left exposed or painted over to match the wall finish.

Where columns occur checkouts are provided; clearances of 1/2″ on each side and 3/8″ on the face side of the column are standard dimensions.

The position of the steel beam at the head section allows the use of eye bolts and dowels at each joint. End head pieces are made with hooks cast in; eye bolts or J-bolts are fastened to this hook and bolted to the steel beam.
