Sugatsune stainless steel piano hinge delivers a continuous 1-1/4 inch wide hinge leaf over an 11-13/16 inch length, so doors or panels swing on a single straight line instead of multiple smaller hinges. This piano hinge is made from 304 stainless steel, giving the leaf and knuckles corrosion-resistant metal that suits demanding shop or site conditions. The hinge uses a double folded construction, which stiffens the leaf across its length so long runs resist flex during repeated operation. Knuckles on both ends are crimped, so the pin is captured at the ends and cannot slide out during use. The hinge pin does not occupy the crimped knuckles on both ends, which leaves the crimped sections dedicated to securing the pin and helps maintain alignment of the rotating knuckles under load.
The 1-1/4 inch wide leaf on this weld-on piano hinge provides edge room for laying out tack points along the 11-13/16 inch length, so the hinge can be aligned straight before final weld passes. Double folded construction stiffens the hinge during handling and welding, helping the knuckles stay in line as heat is applied along the leaf. Because the knuckles at both ends are crimped around the pin, the hinge stays assembled as it is positioned on doors, lids, or frames, which keeps the pivot line intact while you work. With the pin not occupying the end crimped knuckles, the working knuckles carry the rotation while the end crimps act as pin retainers, helping maintain smoother motion once the welded assembly is in service.
This piano hinge, identified as LSN15-32-300, combines a 1-1/4 inch width with an 11-13/16 inch length, making it suited to shorter access doors, lids, or panels that benefit from a continuous pivot line. The 304 stainless steel material works well in shop-built fixtures or cabinets where exposure to moisture, spills, or cleaners is expected, because the hinge parts resist rust. Double folded construction gives the hinge added stiffness, which is helpful on narrower frames or door edges that depend on the hinge to keep the panel running true. Crimped knuckles on both ends retain the pin during fabrication and handling, supporting accurate hinge placement on frames, door leaves, or welded structures that move frequently.
The double folded construction of this stainless steel continuous hinge creates a reinforced leaf profile, so the hinge can better resist bending forces when a door is swung or a lid is opened repeatedly along its 11-13/16 inch length. Because the hinge is made from 304 stainless steel, the knuckles and pin seat in a corrosion-resistant structure, which supports consistent movement even after long-term exposure to typical shop humidity or cleaning cycles. The crimped knuckles at both ends lock the pin in place, so lateral forces on the door do not work the pin outward during use. With the hinge pin not running through the crimped end knuckles, the rotating knuckles carry the movement while the end crimp sections focus on pin retention, helping reduce play at the ends of the hinge during opening and closing.
The LSN15-32-300 hinge has a 1-1/4 inch wide leaf and an 11-13/16 inch overall length, giving a compact continuous hinge section for shorter doors or panels.
The hinge is made from 304 stainless steel, providing corrosion-resistant leaf and knuckles that support long-term use in typical shop or cabinet environments.
The double folded construction stiffens the leaf along its length, helping the hinge resist twisting and flex during repeated door or lid movement.
The knuckles on both ends are crimped to prevent the pin from being removed, so the hinge remains assembled during fabrication and service.
The hinge pin does not occupy the crimped knuckles on both ends, allowing those end knuckles to focus on securely retaining the pin.
This piano hinge suits welded doors, lids, or panels that need a continuous 1-1/4 inch wide stainless steel pivot over an 11-13/16 inch run.
The Sugatsune stainless steel piano hinge LSN15-32-300 combines 1-1/4 inch width, 11-13/16 inch length, and 304 stainless steel in a double folded design, giving a compact continuous pivot solution. Crimped end knuckles retain the pin, supporting stable operation on welded doors or panels where a straight, durable hinge line is required.
