Secondary Lap Rules at a Framed Opening:

Cantilever = When the distance from Jamb to Column 0" - 6'-0".

Simple = When the distance from Jamb to Column 6'-0" - 12'-0".

Continuous Lap = When the distance from Jamb to Column > 12'-0".

Framed Opening Jamb and Header Material Size Progression:

1. Match the secondary depth for the surface, using the smallest available thickness.

2. Use double jambs and/or headers, bar steel primed, using the smallest available thickness.
