Sugatsune HES3D concealed hinge provides a hidden hinge solution for doors using a minimum 1-1/2 inch door thickness, so you can design heavier or thicker doors while keeping the hinge out of sight. This hinge sits in the invisible hinges class, which helps create a clean, uninterrupted door and frame appearance on high-end woodworking and architectural projects. The polished nickel color gives the hinge a bright metallic look that supports jobs where exposed hardware edges or sight lines need a coordinated finish. As a UL rated hinge, it is verified for use on doors requiring up to 3 hours of rated performance, which is important on projects where the hinge must meet a documented standard. This concealed hinge also fits applications where a 3-way adjustable hinge saves time on fine-tuning alignment after hanging the door.
This Sugatsune America hinge is specified as a concealed 3-way hinge, so it provides independent adjustments that help correct door reveal, height, and depth relationships after installation. The minimum door thickness of 1-1/2 inches guides how you build or select the door, aligning the hinge geometry with the edge profile and mortise depth. Hinge leaves that separate mean you can mount one leaf to the frame and the other to the door, then bring the two together on site, which helps when working alone or handling large doors. Cover caps that hide screw heads finish off the hinge pockets, giving the installation a precise, finished look once your alignment work is complete.
The HES3D-E190PN-UL hinge belongs to the invisible hinges category, so it suits projects where the hinge body should remain concealed when the door is closed. The UL rating up to 3 hours supports use on rated doors where a tested hinge is required by the design or specification. A minimum door thickness of 1-1/2 inches fits thicker cabinet doors, passage doors, or architectural panels built with that edge dimension, allowing the hinge body to sit properly within the door and frame pockets. The polished nickel color integrates with projects using polished nickel hardware, helping maintain a consistent visual theme across handles, pulls, and other metal components. Because the hinge leaves separate, the hinge fits workflows that stage frame and door installation separately, such as finishing doors offsite and then re-hanging them later.
The 3-way adjustable feature allows adjustment in three directions, which helps dial in reveals and contact pressure after the door is hung, reducing rework caused by small layout variations. Successfully passing 300,000 open and close private cycle tests indicates the hinge design is intended to withstand frequent operation, which is beneficial on high-use doors in residential or commercial settings. Cover caps that hide all screw heads provide both visual and practical value, since they protect fastener heads inside the hinge mortise and create a clean boundary between the hinge and wood surfaces. The polished nickel finish supports projects where a bright, reflective hinge edge might be visible when the door is open, helping that small detail align with the rest of the job. The Sugatsune America branding links this hinge to a recognized hinge manufacturer, which matters on projects where specified brands are part of the hardware schedule.
The HES3D concealed hinge is specified for a minimum door thickness of 1-1/2 inches, so door construction must meet or exceed that thickness for proper hinge mortising.
The 3-way adjustable design allows fine-tuning in three directions, so you can align reveals and door position after installation rather than altering the mortise layout.
The UL rating up to 3 hours indicates this hinge has been evaluated for use on doors requiring that rating duration, supporting projects with rated door requirements.
The hinge leaves separate so door and frame sides can be mounted independently, which simplifies handling and allows easy removal and re-hanging during finishing or service.
Cover caps hide all screw heads inside the hinge pockets, giving the installation a clean, uninterrupted appearance around the hinge areas on the door and frame.
This hinge is specified in polished nickel color, providing a bright metallic appearance that coordinates with other polished nickel hardware on the same project.
The Sugatsune HES3D concealed hinge with part number HES3D-E190PN-UL combines invisible hinge construction, 3-way adjustability, and a polished nickel color, so it matches projects needing concealed hardware and precise door alignment. The UL rating up to 3 hours supports use on rated door applications, while successful 300,000 cycle testing demonstrates suitability for doors that will see frequent operation. With hinge leaves that separate and cover caps that hide screw heads, this hinge supports efficient installation and a clean finished appearance. Choose this model when you need a concealed hinge for doors built at a minimum 1-1/2 inch thickness with polished nickel hardware.
