Double Action Spring Hinge describes this Sugatsune America hinge that is designed to swing in both directions and return using spring force, which helps doors move freely either way while still coming back to position under controlled tension. The spring loaded for self-closing design means the built-in springs pull the door shut after opening, which reduces doors left ajar in busy traffic areas. Adjustable spring tension lets you fine-tune how firmly the door returns, so you can match the closing force to the door weight and application. The 7-1/16 inch length gives a substantial mounting footprint along the door edge, which helps spread loads for better long-term stability. The 5-1/4 inch width provides generous leaf coverage at the jamb and door, which supports alignment on heavier or taller doors.
The adjustable spring tension feature lets you dial in closing power during installation, which supports a balance between positive closing and manageable opening effort for users. Eight holes in the leaves offer multiple screw points along both door and frame contact areas, which helps achieve secure attachment and reduces hinge shift under repeated use. The 7-1/16 inch overall length gives a longer clamping area on the stile, which can aid in maintaining alignment during double action movement. The 5-1/4 inch width supplies ample surface contact, which contributes to stable mounting when doors are subject to frequent opening from both directions. The double action configuration allows swing in and out from the frame, which supports layouts that rely on two-way movement through the same opening.
This hinge belongs to the Specialty Hinges category, which positions it for applications where conventional single-swing hinges do not provide the needed motion. As a Double Action Spring Hinge, it is intended for openings that benefit from a door swinging both inward and outward, which suits pass-through pathways where traffic flows from either side. The spring loaded for self-closing function supports doors that need to return after passage, which is valuable when maintaining separation between spaces while still allowing frequent access. Its 7-1/16 inch length and 5-1/4 inch width give this Sugatsune double action hinge a substantial footprint, which supports use on doors that experience regular movement through the full double swing range. Eight knuckles in the barrel support the double action rotation, which helps the door travel in both directions with guided alignment.
The adjustable spring tension feature lets installers tune the self-closing behavior of this self-closing double action hinge, which helps align closing speed and force to different door masses and user expectations. Multiple adjustment possibilities mean the same JDA-180-38S hinge can serve a range of door setups, which supports more consistent outcomes across similar openings. Eight holes distributed on the leaves create a wide fastener spread, which helps the hinge resist twisting forces created when doors are pushed from either side. This sturdy pattern works with the broad 5-1/4 inch width to maintain contact across the hinge side, which aids long-term alignment. The eight knuckles create several bearing interfaces within the hinge barrel, which distributes movement loads as the door swings open from either direction. As a Double Action Spring Hinge from Sugatsune America, this unit combines two-way motion with spring loaded for self-closing performance, which supports efficient traffic flow while still returning the door toward its resting position.
This Double Action Spring Hinge is built so the door can swing in both directions using a multi-knuckle barrel, which supports two-way passage through an opening while still using the same hinge point.
The spring loaded for self-closing feature pulls the door back after opening, which helps return doors toward closed position without separate door control hardware.
The adjustable spring tension lets installers change closing force, which helps match door behavior to its size and traffic so operation feels controlled instead of abrupt.
The eight knuckles form the hinge barrel with multiple bearing points, which supports smooth double direction swing and helps distribute stresses from repeated cycles.
The eight holes provide several fastener locations across the hinge leaves, which helps create a secure mount that resists shifting when doors are pushed from both sides.
The 7-1/16 inch length and 5-1/4 inch width give this hinge a broad mounting area, which helps support door alignment and stability in double action applications.
This Double Action Spring Hinge from Sugatsune America pairs double-direction swing with spring loaded for self-closing performance, which supports doors that must open both ways yet still return. With adjustable spring tension and a broad 7-1/16 inch by 5-1/4 inch footprint, it suits openings that see consistent two-way traffic and demand controlled door movement. For projects using specialty double action layouts, the JDA-180-38S hinge supplies the motion pattern and adjustability needed to keep doors operating predictably over repeated cycles.
