Sugatsune satin stainless steel piano hinge gives you a continuous hinge solution for projects that need consistent support along a 70-55/64 inch run. This piano hinge uses double folded construction, so the leaf profile is formed to add extra rigidity, helping the hinge resist flexing along its full length when the door or panel is cycled. The hinge is made from 304 stainless steel, which provides corrosion resistance in demanding shop and field environments where moisture or cleaning chemicals are present. A satin stainless steel finish presents a clean, professional look that suits commercial and architectural applications while matching other stainless components. The hinge width of 1-1/2 inch pairs with the extended length to spread loads evenly, which is useful when you are hanging longer doors, lids, or access panels that should not sag over time.
The SAP description identifies this product as a 1-1/2 inch weld-on piano hinge 70-55/64 inch long, indicating it is intended for weld-on attachment methods rather than screw mounting. This weld-on design lets fabricators integrate the hinge directly into metal frames or doors, which can provide a solid, permanent connection when correctly aligned. The continuous 70-55/64 inch length allows the installer to align the hinge along the full edge of the panel, helping maintain consistent gaps and smooth operation once welded. The 1-1/2 inch width offers a defined bearing surface during layout, so the hinge can be positioned consistently along the edge before welding, supporting repeatable setups across multiple units in the same project.
This hinge is classified as a piano hinge in the Sugatsune America lineup, so it is intended for applications where a continuous hinge is preferred over separate butt hinges. With a length of 70-55/64 inch, it suits tall doors, large access panels, or long lids that benefit from support across the entire edge, helping distribute loads instead of concentrating them at a few points. The 1-1/2 inch width creates a compact footprint that works on narrow frames or door edges while still providing a stable pivot line. Being made from 304 stainless steel, the hinge is suited to environments where standard steel might corrode, supporting use in commercial, institutional, or shop settings where hardware longevity matters. The satin stainless appearance enables this hinge to function both as structural hardware and as a visible component that matches other stainless fittings in the assembly.
The double folded construction that provides extra rigidity directly supports repeatable operation because the hinge resists twisting under load, helping doors or panels track straight over time. The crimped knuckles on both ends that prevent the pin from being removed keep the hinge pin captive, which helps maintain alignment of the knuckles along the full length, so the pivot line stays consistent. Because the hinge pin does not occupy the crimped knuckles on both ends, those crimped sections act as end stops, which helps keep the pin centered and reduces the chance of end-play developing in service. The continuous 70-55/64 inch length works together with this construction to create a single, uninterrupted pivot, allowing the installer to avoid stack-up tolerances that can occur when multiple shorter hinges are aligned. As a 304 stainless steel component, the hinge maintains its structural and aesthetic performance in typical woodworking or metalworking environments, supporting long-term, repeatable results in shops that standardize on this part number.
The piano hinge is described as 1-1/2 inch weld-on and 70-55/64 inch long, so it provides a long, continuous pivot with a 1-1/2 inch width suitable for extended door or panel edges.
The LSN15-38-1800 hinge is made from 304 stainless steel, giving it corrosion resistance and strength that support use in demanding commercial and shop environments.
The double folded construction provides extra rigidity, so the hinge resists bending along its length and helps keep long doors or panels tracking smoothly during repeated use.
The crimped knuckles on both ends prevent the pin from being removed, which helps maintain a secure, continuous pivot line in long-term service without the pin drifting out.
On this hinge, the pin does not occupy the crimped knuckles on both ends, so those crimped sections function as end stops that hold the pin in place during operation.
The SAP description lists it as a 1-1/2 inch weld-on piano hinge, indicating it is intended for weld-on attachment to suitable frames, doors, or panels.
This Sugatsune America satin stainless steel piano hinge, part number LSN15-38-1800, combines 1-1/2 inch width with a 70-55/64 inch continuous length, giving fabricators a weld-on hinge that supports long doors or panels along the entire edge. The double folded construction that provides extra rigidity, together with crimped end knuckles that prevent the pin from being removed, delivers a stable pivot that holds alignment over time. For projects calling for 304 stainless steel construction and a continuous hinge, this piano hinge offers a straightforward way to specify one proven component across multiple openings.
