Sugatsune satin stainless steel piano hinge describes a 2 inch wide, 39-3/8 inch long continuous hinge that spreads load evenly along a door or panel edge, which matters when you want smooth, supported movement over the full height of a cabinet or frame. As a piano hinge in the Hinges|Piano Hinges category, it is designed as a continuous pivot point, which helps keep long or heavy panels aligned over time instead of concentrating stress at two short butt hinges. The hinge is identified by manufacturer part number LSN20-50-1000, so installers can match this specific model when repeating a design across multiple jobs or replacing an existing hinge specified by that part. Classified by Wurth Baer Supply as a 2' weld-on piano hinge at 39-3/8' length, it serves projects where a welded hinge connection is preferred for a solid, permanent mount on metal frames or doors.
This Sugatsune America piano hinge is described as a 2' weld-on piano hinge at 39-3/8' length, which sets it up for projects where the hinge leaf is welded directly to a metal frame, door, or panel instead of being fastened with separate hardware. The continuous 2 inch wide leaf gives welders a generous flat surface for placing weld beads along the hinge line, which supports a straight, aligned installation when tacking and finishing the welds. Because the hinge runs the full 39-3/8 inch span, the pivot axis stays consistent from top to bottom of the opening, which helps doors close true without needing multiple hinge positions laid out and aligned individually.
As a piano hinge in the Hinges|Piano Hinges category, this 2 inch by 39-3/8 inch model fits applications that benefit from a continuous hinge line, such as tall cabinet doors, equipment access panels, or lids that need support along their full length. The product name specifies satin stainless steel, so the hinge surface offers a subdued metallic appearance that works in visible installations where a bright polish is not required, helping it blend with other stainless components. Its 304 stainless steel construction supports use in environments where contact with humidity or cleaning moisture is normal, which keeps the hinge working where plain steel might corrode and affect movement. Because Wurth Baer Supply identifies it as a weld-on piano hinge, it suits metal fabrication or shop-built enclosures where the hinge becomes part of the structure through welding. The continuous length also supports retrofits where an existing piano hinge is being replaced with the specified 39-3/8 inch size.
The double folded construction that provides extra rigidity means each hinge leaf has added structural depth, so the leaf resists twisting when doors are cycled, which helps keep the pivot line stable along the full 39-3/8 inch length. That rigidity is useful on wider or heavier doors because it helps distribute the load evenly across the knuckles, supporting smoother operation over the hinge life. The knuckles on both ends are crimped to prevent the pin from being removed, which locks the assembly so the pin cannot slide out at the ends during use. This end crimping matters on welded installations, where the hinge becomes permanent and the door relies on the pin staying captured inside the knuckles. Because the hinge pin does not occupy the crimped knuckles on both ends, the crimped sections act purely as retainers while the central knuckles handle rotation, which promotes predictable pivot action while still holding the pin. Combined with 304 stainless steel construction, these details give installers a hinge that maintains its pivot function and alignment under repeated opening cycles in typical woodworking and metalworking environments.
The Sugatsune LSN20-50-1000 piano hinge is 2 inches wide and 39-3/8 inches long, so it spans a tall panel edge and spreads load along a broad mounting surface.
The hinge is made from 304 stainless steel, which offers corrosion resistance and helps the hinge maintain function and appearance in typical moist or cleaned environments.
The double folded construction provides extra rigidity in the leaves, so the hinge resists flexing under door load and supports smoother, more consistent door movement.
The knuckles on both ends are crimped to prevent the pin from being removed, so the pin stays captured during service and helps keep the hinge assembly intact.
On this hinge, the pin does not occupy the crimped end knuckles, so those knuckles act as retainers while central knuckles handle rotation for consistent pivot action.
The SAP description lists it as a weld-on piano hinge, so it is intended for welded attachment to metal frames or doors where a permanent continuous hinge is needed.
The Sugatsune satin stainless steel 2 inch by 39-3/8 inch piano hinge LSN20-50-1000 combines continuous length, double folded rigidity, and crimped pin retention, which supports long, stable door or panel movement. For welded metal cabinets, enclosures, or access doors where a 304 stainless steel continuous hinge is specified, this weld-on piano hinge from Wurth Baer Supply offers the defined width, length, and construction needed to repeat the same hinge geometry across multiple openings on a project.
