Sugatsune stainless steel piano hinge uses a double folded construction to create extra rigidity along the full 39-3/8 inch length, which helps doors and panels stay aligned on longer runs where standard flat hinges can flex. The 1-1/2 inch wide leaf profile spreads load across a broader surface, supporting heavier or taller doors without concentrating stress in a short hinge area. This piano hinge is made from 304 stainless steel, so the leaf and knuckles resist corrosion in typical shop, cabinet, and light industrial environments that see humidity or cleaning chemicals. The knuckles on both ends are crimped to prevent the pin from being removed, which keeps the hinge assembly intact during service and helps deter casual tampering. Because the hinge pin does not occupy the crimped knuckles, the active bearing area stays consistent for smoother swinging motion over time.
The SAP description identifies this product as a 1-1/2 inch weld-on piano hinge at 39-3/8 inch length, so it is intended for applications where the leaf is permanently attached to metal frames or structures by welding. The consistent 1-1/2 inch width gives a predictable reference for aligning the hinge along door and frame edges, which simplifies layout before welding. Using 304 stainless steel for the hinge means the material is compatible with common stainless structural members, supporting matching weld behavior and finished appearance. The full-length piano hinge format reduces the number of weld points compared with multiple separate hinges, streamlining fabrication while still providing continuous support along the opening edge.
This Sugatsune America piano hinge, identified by part number LSN15-38-1000, belongs to the piano hinges category, so it suits continuous-hinge applications on doors, lids, and panels that benefit from full-height support. The 39-3/8 inch length matches many medium cabinet or access door sizes, allowing the hinge to run nearly the entire stile for stable movement. Because the hinge is made from 304 stainless steel, it is suited to woodworking and light industrial environments handled by distributors such as Wurth Baer Supply that serve professional shops. The 1-1/2 inch width gives enough leaf surface for welding to structural members, which supports use on fabricated enclosures, equipment guards, or storage doors where a narrow leaf would not offer sufficient weld area.
The web description specifies that the double folded construction provides extra rigidity, which helps the leaf resist twisting when welded along a long edge, so door clearances stay more consistent from top to bottom. With the hinge pin not occupying the crimped knuckles on both ends, the working knuckles remain uniform, supporting smoother rotation and reducing the chance of binding at the ends of travel. The crimped end knuckles that prevent pin removal keep the hinge functioning as a single unit during handling, welding, and installation on the door and frame, which simplifies alignment because the pin and leaves stay together. Together, the 1-1/2 inch width, 39-3/8 inch continuous length, and rigid double folded construction help fabricators create repeatable hinge lines across multiple identical doors with minimal adjustment after welding.
The hinge has a 1-1/2 inch width and 39-3/8 inch length, giving continuous support along most medium-height doors and providing enough leaf area for secure welding.
The LSN15-38-1000 hinge is made from 304 stainless steel, which supports corrosion resistance and a consistent appearance in typical shop or cabinet environments.
The double folded construction provides extra rigidity, so the hinge leaf stays straighter along its length, helping welded doors swing smoothly without mid-span flex.
The hinge has knuckles on both ends crimped to prevent the pin from being removed, so the assembly stays intact during handling and regular operation.
The hinge pin does not occupy the crimped end knuckles, keeping the working knuckles uniform and helping the hinge swing smoothly along its active length.
This 1-1/2 inch weld-on piano hinge lets fabricators attach a single continuous hinge instead of spacing multiple short hinges, simplifying layout and welding steps.
This Sugatsune stainless steel piano hinge combines 1-1/2 inch width, 39-3/8 inch length, and double folded construction to support rigid, continuous hinging on welded doors and panels. The 304 stainless steel material and non-removable pin design keep the assembly stable in service, while the piano hinge format helps maintain consistent gaps and swing. For projects that call for a weld-on stainless hinge with full-length support rather than separate butt hinges, this LSN15-38-1000 model from Wurth Baer Supply offers a focused solution.
