Double Action Spring Hinge For Self-Closing Doors

double action spring hinge describes this Sugatsune America JDAW-120-35A hinge, which is a spring loaded double action spring hinge designed to provide self-closing action in both directions for swinging doors in woodworking and similar installations. The 4-3/4 inch size gives a substantial bearing surface, which supports stable movement where a compact but capable hinge is required. The hinge is spring loaded for self-closing, so doors return to center after use, helping keep doorways clear in busy work areas. The self closing with adjustable closing speed feature allows the closing speed to be tuned at install time, helping match different door weights or user preferences. As a double action spring hinge in the Specialty Hinges category, it is suited for situations where the door must open both ways and then return to a closed position without manual repositioning.

Key Spring Hinge Details For Job Planning

• The hinge is spring loaded for self-closing, which lets doors return to a closed position automatically and reduces the need for manual door positioning in repetitive-use openings.
• The self closing with adjustable closing speed design allows fine-tuning of the return speed, helping match the motion to door weight and reducing slamming in typical woodworking or shop environments.
• The alumite finish provides a defined surface treatment that gives a consistent appearance, supporting coordinated hardware looks across multiple doors in the same project.
• The hinge has 8 knuckles, creating multiple bearing points that support smooth double action movement where doors need to swing in both directions.
• The hinge has resistance to bending, which supports consistent alignment over time and helps the door track correctly through repeated cycles in service.
• Holes are provided for #8 flathead countersunk screws, 3/4 inch or longer, which suits common fastening practice into wood doors or frames.

Wall Mounted Double Action Hinge Installation Focus

This double action spring hinge is specified as a hinge that can be wall mounted, so it is suited for mounting a door leaf to a wall or similar structure where a jamb may not be used. The requirement for (8) #8 flathead countersunk screws, 3/4 inch or longer, defines the fastening pattern and helps plan for a secure, flush-mounted installation. The 8 knuckles distribute load along the hinge length during mounting, so alignment along the door edge and wall surface stays more consistent. Because the hinge is spring loaded for self-closing, positioning during installation directly affects how the door returns to center, so the physical mounting location and orientation play a practical role in the final swing behavior.
