Sugatsune satin stainless steel piano hinge defines a continuous hinge solution built for welded installations where alignment matters along the full run. This piano hinge uses double folded construction, which adds extra rigidity along the 39-3/8 inch length so doors or panels track on a straighter line under load. The hinge is made from 304 stainless steel, giving corrosion-resistant performance in typical woodworking or light fabrication environments where moisture or cleaning is present. A nominal 1 inch width provides a predictable footprint, helping fabricators size door edges and frames around a consistent hinge strip. The manufacturer part number LSN8-25-1000 ties this hinge to Sugatsune Americas catalog, simplifying repeat ordering when multiple identical hinges are required on a project or across jobs.
The SAP description identifies this as a 1 inch weld-on piano hinge with a 39-3/8 inch length, giving installers a clear footprint for planning weld beads along the frame and leaf. Being a weld-on design means the stainless steel construction integrates directly with compatible metal frames or doors, creating a continuous hinge connection along the entire run. The 1 inch width supports predictable edge reveals, since fabricators can size their door and frame relationship around that fixed hinge band. With the hinge pin secured by crimped end knuckles, the assembly is configured as a permanent pivot, which suits doors or panels expected to stay paired with their frames over time.
The description as a weld-on piano hinge positions this Sugatsune America part for metal cabinet doors, lids, and panels that need a continuous pivot line instead of discrete butt hinges. Its 39-3/8 inch length lets fabricators span most medium-width openings with a single hinge strip, which simplifies alignment by removing hinge spacing calculations. The 1 inch width creates a narrow, consistent mounting band that works well on frame members where available edge surface is modest but still needs full-height support. Because it is made from 304 stainless steel with a satin stainless steel identity, the hinge matches projects where stainless components are used for appearance and corrosion resistance, helping maintain a uniform hardware look along the door edge.
Double folded construction providing extra rigidity is valuable on taller doors or panels that might otherwise twist under use, because the reinforced piano hinge section resists flex better than a single-thickness strip. Crimped knuckles at both ends are built to prevent the pin from being removed, which is useful in service areas where a removable pin could lead to unintended door removal. Since the hinge pin does not occupy the crimped knuckles, installers gain predictable movement across the working knuckles, making it easier to plan clearances at the top and bottom of the door. The specific manufacturer part number LSN8-25-1000 lets shops standardize on this hinge for repeated builds, reducing variation in performance and simplifying reorders for matching doors or future expansions.
The Sugatsune satin stainless steel piano hinge is made from 304 stainless steel, which provides corrosion resistance and a compatible surface for weld-on installations in many metal cabinet and panel projects.
The LSN8-25-1000 hinge has a nominal 1 inch width and a 39-3/8 inch length, giving installers a continuous hinge strip sized for medium-width doors and panels needing full-height support.
The double folded construction gives the piano hinge extra rigidity, so doors or lids stay straighter along the pivot line and resist flexing during repeated opening and closing cycles.
The knuckles on both ends are crimped to prevent the pin from being removed, creating a captive pin arrangement that keeps the door permanently paired with its frame in service.
The hinge pin does not occupy the crimped knuckles, so the active pivot occurs only in the central knuckles, which supports smoother motion and predictable end clearances for the door.
The web description states that it is sold in both broken and full box quantities, which lets shops order closer to their exact hinge count per project or inventory plan.
This 1 inch weld-on piano hinge from Sugatsune America combines 304 stainless steel construction, double folded rigidity, and crimped captive pin ends in a 39-3/8 inch run suited to continuous door support. When a project calls for a stainless steel piano hinge that welds directly to frames and panels, the LSN8-25-1000 configuration offers a defined size and construction pattern that can be repeated confidently across similar builds.
