Sugatsune satin stainless steel piano hinge provides continuous support along a 70-7/8 inch run, which helps spread loads evenly over doors, lids, or panels where point hinges would concentrate stress. The 1-1/4 inch width creates a broad bearing surface, giving fabricators a stable hinge line when aligning long edges before final welding. This piano hinge is made from 304 stainless steel, so it resists corrosion in many indoor and certain sheltered environments, supporting long-term operation where moisture or cleaning routines are present. The weld-on designation in the description means installers can integrate the hinge directly into metal frames or structures, which is useful when screw mounting is not part of the design. As a product from Sugatsune America in the piano hinge class, it fits projects where a straight, accurate hinge axis is needed across the full door or panel length.
The description listing this as a 1-1/4 inch weld-on piano hinge guides fabricators toward metal doors, lids, or access panels where welding is part of the build sequence. With its 70-7/8 inch length, the hinge can be positioned and clamped along a long edge, so installers can check swing clearance and panel reveal before committing to final welds. The double folded construction adds rigidity along the barrel, which helps the hinge stay straight when welded in sections instead of a single continuous pass. Because the material is 304 stainless steel, the hinge can be paired with compatible stainless framing for a consistent weld pool and appearance along the joint.
This piano hinge belongs to the hinges and piano hinges category, positioning it for situations where a continuous pivot is preferred over individual butt hinges. The 1-1/4 inch width lets metalworkers set the hinge along door or panel edges on equipment housings, storage enclosures, or service access doors where weld-on construction is used. At 70-7/8 inches, the hinge can span tall cabinet-style openings or wide lids, creating consistent movement along the full edge as the panel opens and closes. The 304 stainless steel material and satin stainless steel finish keep the hinge suitable for installations where appearance and resistance to ordinary moisture are part of the project requirement. In these contexts, the hinge delivers a straight, controlled pivot line on fabricated assemblies that rely on welded connections rather than mechanical fasteners.
Double folded construction provides extra rigidity throughout the hinge length, which helps the barrel stay aligned even when welded in multiple segments or when the door weight loads the hinge unevenly. The knuckles on both ends are crimped to prevent the pin from being removed, so the hinge pin stays captured during normal operation and resists axial movement that might otherwise lead to misalignment. The hinge pin does not occupy the crimped knuckles on both ends, which means the crimped sections serve as end-stops while the central knuckles carry the pivot action, promoting smoother rotation along the working span. As a Sugatsune America product with manufacturer part number LSN8-32-1800, this hinge gives installers a precise reference when they need to repeat a specification, match an existing hinge on additional openings, or document hardware in project records. Together, these construction characteristics support consistent performance where a welded, continuous stainless steel hinge line is required on fabricated assemblies.
The Sugatsune satin stainless steel piano hinge measures 1-1/4 inches in width and 70-7/8 inches in length, giving fabricators a long, continuous pivot line for doors or panels.
The piano hinge is made from 304 stainless steel, which supports corrosion resistance and long-term use in many indoor and sheltered metal fabrication applications.
The double folded construction provides extra rigidity along the hinge, helping maintain a straight pin line and smoother operation on long doors or panels.
The crimped knuckles on both ends prevent the pin from being removed, keeping the hinge pin captured so the hinge remains assembled during normal use.
The hinge pin does not occupy the crimped knuckles on both ends, so those knuckles act as pin stops while the central knuckles handle the actual pivoting motion.
This 1-1/4 inch weld-on piano hinge suits metal doors, lids, or access panels where a continuous 70-7/8 inch stainless steel hinge line is required.
The Sugatsune satin stainless steel piano hinge with part number LSN8-32-1800 combines a 1-1/4 inch width, 70-7/8 inch length, and weld-on design, giving metalworkers a defined solution for continuous stainless steel pivot lines. Its 304 stainless steel construction and double folded design support both corrosion resistance and structural rigidity along the entire hinge run. Crimped end knuckles that secure the pin simplify planning around long-term operation, since the hinge pin remains captured within the assembly. For projects calling for a continuous stainless steel piano hinge across doors, lids, or access panels, this model provides a clear, repeatable specification to apply.
