Installation & Operation

1. Review manufacturer specifications and verify door preparation requirements including door thickness, weight capacity (45-70 lbs), and mortise dimensions for proper hinge installation.
2. Use manufacturer-provided templates to mark mortise locations accurately on both door and frame, ensuring proper alignment for 3.5" x 3.5" or 4" x 4" hinge size.
3. Prepare door and frame by routing mortise pockets to accommodate full mortise installation with 5/8" radius corners.
4. Install hinges using appropriate wood fasteners (3-1/2" doors use 3/4 X 9 screws, 4" doors use 1 X 9 screws) and secure per manufacturer torque specifications.
5. Adjust spring tension as needed - full spring tension may not be required on all hinges depending on door weight and environmental conditions.
6. Test door operation to verify proper self-closing function and smooth operation throughout full range of motion. Consider wind conditions, drafts, and carpeting drag when making final adjustments. Refer to manufacturer documentation for complete installation details.
