Double Action Spring Hinge Self-Closing 7-1/16"L x 4"W Anodized from Sugatsune America is a double action spring hinge designed to swing in both directions, so a door can open either way through a doorway and then return to center. As a spring loaded hinge with self-closing action, it uses internal spring force to pull the door back after movement, which helps keep walk-through areas consistently closed without relying on users to shut the door. The adjustable spring tension feature lets you set the closing force to match the door weight and opening pattern, which is useful where different traffic levels or door sizes demand a specific closing speed. Classified as a specialty hinge within the Hinges category, it suits projects that call for controlled two-way movement instead of standard one-way swinging doors.
This double action spring hinge mounts using the eight holes in its leaves, giving multiple points to fasten the hinge to the door and frame so the swinging movement stays aligned under load. The 7-1/16 inch length and 4 inch width define the mounting footprint, which matters when matching the hinge to the door stile and frame space during layout. As an adjustable spring tension hinge, it allows the installer to increase or reduce spring force, which helps tune the self-closing action so doors return smoothly without excessive slam. The spring loaded design also means closing force comes from internal springs rather than external door closers, which can simplify how the door assembly is planned in a woodworking or hardware installation.
As a Double Action Spring Hinge Self-Closing 7-1/16"L x 4"W Anodized unit, this hinge is suited to doors that need to swing both inward and outward while still returning toward a closed position, which is common in pass-through openings. Being part of the Hinges | Specialty Hinges category, it targets applications that require more than simple pivoting, such as work areas where two-way access is needed without leaving doors resting open. The double action spring hinge configuration provides motion in both directions from a single hinge line, which helps reduce hardware complexity compared with separate mechanisms on each side of the opening. Its eight knuckles form a continuous pivot assembly, which keeps the door movement guided along a single axis as people move through.
The Sugatsune America JDA-180-30A designation identifies this specific double action spring hinge, which helps match the hinge to project documents or repeat orders when consistent performance is required across multiple openings. The adjustable spring tension allows fine-tuning of self-closing behavior, which helps achieve a repeatable door return speed across similar doors in the same project. With eight holes available for mounting, the hinge lets installers place fasteners across the length of the leaves, which supports consistent alignment and reduces the chance of the hinge shifting over time under back-and-forth traffic. The anodized finish on the hinge surface supports long-term appearance, which matters when the same hinge style is used across a visible bank of doors. Its role as a spring loaded, self-closing specialty hinge means it can serve as a key functional component in door assemblies where controlling how doors return after being pushed from either direction is important for workflow and space management.
The Sugatsune America JDA-180-30A is a double action spring hinge, so it lets a door swing in both directions and then return toward the closed position using its internal springs.
The hinge is spring loaded for self-closing, meaning built-in springs apply force to pull the door back after opening, which helps keep the doorway consistently returned toward closed.
This double action spring hinge has adjustable spring tension, so the closing force can be set to better match door weight and desired closing speed in a given application.
The hinge measures 7-1/16 inches in length and 4 inches in width, which defines the mounting footprint available on the door stile and frame edge.
The eight holes provide multiple fastening points along the leaves, spreading the load across the door and frame so the hinge stays secure during repeated two-way swinging.
The anodized finish gives the hinge a treated surface, supporting appearance and surface integrity where doors are operated frequently in woodworking or similar environments.
The Sugatsune America Double Action Spring Hinge Self-Closing 7-1/16"L x 4"W Anodized combines two-way swing, adjustable spring tension, and a defined 7-1/16 inch by 4 inch footprint, which helps align hardware selection with your door size and movement needs. Its eight knuckles and eight mounting holes support stable, guided motion that suits repeated passage in work areas. When a project calls for a specialty hinge that can open both ways and then return toward closed using spring force, this JDA-180-30A double action spring hinge offers a structured, part-numbered option for consistent use across similar openings.
