Sugatsune satin stainless steel piano hinge delivers a continuous hinge solution in a 1-1/4 inch width and 39-3/8 inch length, which spreads loads along the full edge and supports long doors, lids, or panels without concentrating stress at short hinge points. This hinge is made from 304 stainless steel, which resists corrosion in typical shop, cabinet, and light industrial environments, so hinge performance remains consistent over time. The construction is described as double folded, which increases rigidity along the hinge leaf and knuckle line, giving better support where doors see repeated opening and closing. The satin stainless finish presents a clean, uniform appearance that pairs well with stainless or neutral-toned projects while helping minor handling marks blend into the surface. As a piano hinge in the Sugatsune America line, this part supports projects that call for continuous support rather than discrete butt hinges.
The SAP description identifies this part as a 1-1/4 inch weld-on piano hinge in a 39-3/8 inch length, indicating it is intended for welding to the mating surfaces instead of screw mounting, which integrates the hinge solidly into metal frames or doors. By using a weld-on style, the installer can position the 304 stainless steel leaves exactly along the desired pivot line and tie the hinge directly into structural members, supporting consistent alignment. The continuous 39-3/8 inch length gives a long, uninterrupted weld area, which distributes door or lid forces along the full run instead of at a few discrete hinge points.
This hinge is classified as a piano hinge within the Hinges piano hinge category, indicating it is suited to applications where a full-length pivot is required, such as long doors, lids, or panels that benefit from continuous support. The 1-1/4 inch width provides a modest leaf projection that works well where space around the door edge is limited yet continuous support is needed. At 39-3/8 inches long, the hinge can span many medium-height doors or lids with a single piece, avoiding breaks that could introduce misalignment. Because the hinge is made from 304 stainless steel and finished in satin stainless, it suits projects that pair stainless hardware with cabinetry or enclosures for a unified material palette. The weld-on identification in the SAP description aligns this hinge with metal frames or doors where welding is the preferred attachment method.
The double folded piano hinge construction increases leaf rigidity, which helps the hinge stay straight during fit-up and welding, reducing the tendency for distortion along the pivot line. Crimped knuckles on both ends that prevent pin removal keep the hinge pin captured while tack welding and final welding are carried out, so the knuckle alignment is preserved as heat is applied. Because the hinge pin does not occupy the crimped end knuckles, those crimped sections act as end restraints while leaving the working knuckles free to rotate, which supports smooth motion after installation. The 1-1/4 inch width and continuous 39-3/8 inch length provide a predictable edge reference when aligning the hinge to door and frame edges before welding. Using 304 stainless steel for the hinge body and pin supports a consistent material during welding on stainless structures, which can help maintain a uniform appearance at the hinge line. These combined characteristics make the LSN8-32-1000 part number a practical piano hinge choice for continuous welded installations that need repeatable movement.
This Sugatsune satin stainless steel piano hinge is 1-1/4 inches wide and 39-3/8 inches long, so it spans a significant door or panel height with a single continuous pivot line.
The LSN8-32-1000 piano hinge is made from 304 stainless steel, providing corrosion resistance that supports performance in typical shop, cabinet, or light industrial environments.
The double folded construction provides extra rigidity, helping the hinge resist flexing along its length so long doors or panels stay aligned through repeated opening and closing.
The crimped knuckles on both ends prevent the pin from being removed, keeping the pin retained during operation and handling where a loose pin could cause hinge failure.
On this hinge the pin does not occupy the crimped knuckles, so those end knuckles act as captive stops while the central knuckles carry rotation for smooth motion.
This piano hinge is identified by Sugatsune America as LSN8-32-1000 and appears in the hinges piano hinge category, which helps align it with continuous hinge applications.
The Sugatsune satin stainless steel 1-1/4 inch by 39-3/8 inch piano hinge brings double folded construction, crimped-end pin retention, and 304 stainless steel material together in one continuous hinge, giving installers a defined part for welded stainless door and lid projects. Choosing the LSN8-32-1000 part number allows projects that need a weld-on, full-length stainless hinge to standardize on a single size and construction style for consistent results across multiple openings.
