1. SCOPE AND PURPOSE 1.1 This Standard covers all significant dimensional attributes for mounting common hardware products in wood doors and metal or wood frames. All dimensions shall be as shown on the accompanying drawings. 1.2 This standard was developed to show only the most commonly used preparations for door hardware, and provide targets for standardization. Where multiple configurations are in common usage, separate drawings are provided. For other configurations, it is recognized that these standards may be used in part, or with exceptions, while still providing some degree of basic guidance and standardization.
