**[STEEL DOORS AND FRAMES]{.underline}**

**\*\*\*\*\* This guide section can be used for specifying various types
of hollow steel doors and frames for construction projects at SNL. The
specifier will need to edit this section for a specific project to
reflect the options and applications being used. The guide section has
been written so that most editing can be accomplished by deleting
unnecessary requirements and options. Depending on project requirements,
some additional information will need to be added by the specifier.
Options are indicated by \[ \]. Notes to assist the specifier in
selecting options and editing the specification guide are printed in
bold and indicated with \*\*\*\*\*. For final editing, all brackets and
notes will need to be deleted from the guide, and this specification
will need to be made into a Construction Special Specification.**

**Throughout this product guide specification, references are made to
other specification sections that might be contained in the project
manual. These references are presented as examples and coordination
reminders. \*\*\*\*\***
