Sugatsune satin stainless steel piano hinge describes a 1 inch wide, 23-5/8 inch long stainless steel piano hinge designed as a continuous hinge, so doors or panels carry load along the full length instead of concentrated points at discrete hinges. The piano hinge uses double folded construction, which forms a reinforced profile along the barrel, giving extra rigidity so metal fabrications or enclosures resist twisting or sagging along the hinge line. The hinge is made from 304 stainless steel, which provides corrosion-resistant performance in typical indoor and many sheltered shop environments where moisture or cleaning agents are present. This model is identified by manufacturer part number LSN8-25-600 from Sugatsune America, so installers can match it to drawings or prior orders when repeating a fabrication. The product is classified under piano hinges, keeping it aligned with continuous-hinge applications on longer doors, hatches, or lids where smooth, even movement is required.
This 1 inch wide, 23-5/8 inch long piano hinge is described as a weld-on piano hinge, so fabricators can attach it directly to metal doors or frames using welding processes rather than relying on separate fasteners. The continuous length allows alignment along the full door edge, supporting a consistent reveal when the hinge is positioned straight against the mating surface. The double folded construction provides extra rigidity during welding, which helps the hinge barrel hold shape while heat is applied along portions of its length. The crimped knuckles on both ends keep the pin captive throughout handling, allowing installers to weld and align the hinge without dealing with a loose pin during fit-up.
This Sugatsune America piano hinge, made from 304 stainless steel, performs well in typical woodworking shops or metal fabrication environments where cabinets, enclosures, or covers benefit from a continuous stainless hinge line. The 23-5/8 inch length suits shorter doors, access panels, or lids, so the entire edge gains support from one hinge piece. The 1 inch width keeps the profile compact, which suits narrow frames or small flanges on fabricated doors. Double folded construction provides extra rigidity along the hinge, supporting panels that may see frequent cycling or moderate loads, while still working within tight clearances. Because the hinge pin is retained by crimped knuckles on both ends, it is suited to applications where staying captive is important, such as equipment doors that must remain intact during vibration or regular use.
The weld-on description means installers can position this piano hinge exactly where needed on steel or compatible metal frames, then weld along selected sections to fix alignment, giving consistent reveals from job to job. Double folded construction adds stiffness to the hinge barrel, which helps maintain straightness during welding and reduces distortion that could cause binding. The knuckles on both ends are crimped to prevent the pin from being removed, which keeps the hinge as a single assembly throughout handling and service, supporting predictable performance on repeat builds. Because the hinge pin does not occupy the crimped knuckles, the hinge relies on the formed end knuckles as stops, which reduces direct impact on the pin ends and supports smoother rotation over time. Using the specific manufacturer part number LSN8-25-600 helps fabricators reorder the exact same hinge for future builds, keeping movement, clearances, and aesthetics consistent across multiple installations.
The LSN8-25-600 piano hinge is 1 inch wide and 23-5/8 inches long, so it covers the full edge of shorter doors or panels with a compact continuous hinge line.
The hinge is made from 304 stainless steel, providing corrosion-resistant performance for typical indoor or sheltered shop environments where moisture or cleaning is present.
The double folded construction provides extra rigidity along the hinge barrel, so longer or heavier doors resist twisting and maintain smoother swinging movement under load.
The knuckles on both ends are crimped to prevent the pin from being removed, keeping the pin captive for tamper resistance and preventing pin loss during service.
The hinge pin does not occupy the crimped end knuckles, so the formed metal ends act as stops, reducing direct wear on the pin tips during repeated cycling.
This 1 inch wide piano hinge is described as a weld-on hinge, so it is attached by welding to compatible metal doors and frames for a permanent continuous hinge joint.
This 1 inch by 23-5/8 inch Sugatsune satin stainless steel piano hinge offers double folded construction for extra rigidity, 304 stainless steel for corrosion resistance, and crimped end knuckles that hold the pin captive. The weld-on design suits metal fabrication where a continuous, permanent hinge line is preferred over individual hinges. For projects using shorter doors, lids, or panels that benefit from a compact continuous hinge in 304 stainless, this LSN8-25-600 piano hinge provides a defined size and construction style that aligns with repeatable shop work and consistent movement.
