Single Action Spring Hinge Self-Closing 8 Holes, 6 Knuckles 3-1/8"W Stainless Steel

Single Action Spring Hinge For Self-Closing Doors

Single Action Spring Hinge describes this Sugatsune America JSA-180S hinge as a spring-loaded, single-direction door hinge that closes the door automatically, which is useful where doors need to return to a closed position without manual effort. The self-closing function is created by the spring loaded design, which pulls the door shut after opening and helps maintain consistent door position between uses. The adjustable closing speed lets the installer tune how quickly the door swings shut, which helps match the closing action to the door weight and application. The hinge width of 3-1/8 inches defines its footprint on the mounting surface, which matters when laying out screw locations on the door and wall. The stainless steel material provides a durable hinge body, which suits areas where metal strength is important during repeated door operation.

Key Spring Hinge Details That Support Daily Use

• The spring loaded design provides automatic self-closing action, which helps keep doors shut after each opening without relying on users to pull them closed.
• The adjustable closing speed feature allows fine tuning of door movement, which helps reduce slamming and supports smooth operation across different door weights.
• The hinge is described as having resistance to bending, which supports performance under repeated swings and helps maintain door alignment over time.
• The hinge can be wall mounted, which gives flexibility in mounting a door or panel directly from a wall surface where this style of hinge is preferred.
• The hinge uses eight #8 flathead countersunk screw points, which spreads load over multiple fasteners and supports stable mounting when installed on suitable substrates.
• The stainless steel construction combined with the alumite finish creates a robust hinge body, which supports long-term service where a metal hinge is required.

Wall Mounted Spring Hinge Installation Details

This Sugatsune America JSA-180S spring hinge is designed so the hinge can be wall mounted, which lets the installer fasten one leaf to a wall surface when hanging a door or panel in that orientation. The requirement for eight #8 flathead countersunk screws, 3/4 inch or longer, defines the fastener size and minimum length, which helps with planning drilling patterns and selecting appropriate mounting points on the door and wall. The 3-1/8 inch hinge width provides a known dimension across the leaves, which aids layout when aligning the hinge vertically and horizontally on the mounting surfaces. The spring loaded, self-closing action operates in a single direction, which suits applications where the door is intended to swing one way and return to the closed position after being opened.

How This Self-Closing Hinge Works In Practice

Where The Sugatsune JSA-180S Spring Hinge Fits

The Sugatsune America JSA-180S is classified as a Single Action Spring Hinge, which indicates it is used on doors that swing in one direction and then return toward closed under spring tension. Being part of the Hinges and Specialty Hinges category places it among hardware used where a standard butt hinge is not sufficient and a self-closing function is desired. The ability for the hinge to be wall mounted means it fits situations where a door or panel is supported directly from a wall rather than only from a cabinet frame, which broadens its application options. The hinge width of 3-1/8 inches sets a compact footprint, which fits many small to medium door or panel layouts where space around the jamb is limited yet a spring hinge is required.

Why Adjustable Closing And Strength Details Matter

The self closing with adjustable closing speed feature lets the installer set how firmly the spring pulls the door shut, which helps balance closing force against user comfort and the specific door mass. This adjustable closing speed also assists with reducing impact when the door reaches the frame, which can support smoother operation in high-use environments. The description noting resistance to bending points to a hinge structure designed to handle repeated loading, which helps maintain consistent door alignment after many open-and-close cycles. The stainless steel construction works together with this resistance to bending, which supports a hinge that maintains shape under normal door use. The eight-hole pattern for #8 flathead countersunk screws distributes the load over multiple points, which contributes to a solid mount when the hinge is installed on appropriate materials. The alumite finish on the hinge complements the stainless steel body, which provides a finished surface suited for visible mounting locations where appearance of the hinge matters alongside function.
