**[WOOD DOORS]{.underline}**

\*\*\*\*\* This guide section can be used for specifying fire-rated and
non-rated, interior, flush, solid core, wood doors for construction
projects at SNL. Exterior and hollow core wood doors are not used for
SNL projects. 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. \*\*\*\*\***
