(Specifier Note: The purpose of this guide specification is to assist the specifier in correctly specifying utility hoisting systems and their installation. The specifier needs to edit these guide specifications to fit the needs of each specific project. Contact a Draper, Inc. representative to assist in appropriate product selections. Throughout the guide specification, there are Specifier Notes to assist in the editing of the file. The term Architect is used throughout these guide specifications and may be revised to read “Design Professional”,” Engineer”, “Owner” or other appropriate designation as required for specific projects.

References have been made within the text of the specification to MasterFormat 2004 Section numbers and titles; specifier needs to coordinate these numbers and titles with sections included for the specific project. Brackets have been used to indicate when a selection is required, in most cases the first option is the standard feature.)
