Sugatsune HES2S concealed hinge is a surface mount invisible hinge designed for 1-1/2 inch thick doors and heavier applications. This hinge surface mounts to the door frame, so it creates an invisible hinge look while staying accessible from the frame side during layout and adjustment. The compact and sturdy design supports substantial door weight, which suits larger cabinet, panel, or interior utility doors that need a clean appearance. The hinge opens to 125 degrees, giving wide access into the opening for loading, service, or hardware work. A door stopper is required to protect the hinge from over-travel, which helps maintain hinge integrity over repeated cycles. The light gray finish gives a neutral, worklike appearance that blends into many casework and frame finishes without drawing attention to the hardware.
This adjustable concealed hinge surface mounts to the door frame, so layout focuses on accurate frame positioning instead of cutting deep pockets in the door. The hinge provides adjustable depth of plus or minus 1/8 inch (3 mm), which lets installers fine-tune how the door sits in relation to the frame reveal after mounting. Vertical adjustment of plus or minus 1/8 inch (3 mm) helps correct sag, joint alignment, or floor variations without redrilling the frame. Horizontal adjustment of plus or minus 1/16 inch (1 mm) with a spacer allows small in-and-out corrections at the hinge line, useful for bringing the door edge flush with adjacent panels. These adjustment ranges let installers dial in gaps and clearances after hanging, which can reduce rework when coordinating multiple doors or uneven framing.
This Sugatsune America HES2S Series hinge is built for doors with a minimum thickness of 1-1/2 inch (38 mm), so it fits thicker panels, heavy cabinet doors, and similar applications that need more edge material. With two hinges supporting a maximum door weight of 110 lbs, installers can hang substantial doors using a standard two-hinge layout in many situations within that weight range. When three hinges are used, the maximum door weight increases to 143 lbs, which helps on taller or denser doors where extra vertical support is beneficial. The invisible hinge style keeps the hardware concealed when the door is closed, which helps achieve a clean, uninterrupted surface on both the door and surrounding casework. The hinge opens to 125 degrees, which gives the door wide travel without swinging completely back onto adjacent structures, suitable for many cabinetry, closet, or equipment access doors.
The adjustable depth of plus or minus 1/8 inch (3 mm) lets installers move the door closer to or farther from the frame surface, which helps align the door face with nearby fronts or trim. Vertical adjustment of plus or minus 1/8 inch (3 mm) provides a way to correct small measurement differences after installation, so the top and bottom gaps can be balanced without shifting the frame. Horizontal adjustment of plus or minus 1/16 inch (1 mm) using a spacer allows slight side-to-side corrections at the hinge, helping achieve consistent reveals between paired doors or between a door and fixed panels. Requiring a door stopper to prevent breakage protects the hinge from being forced past its 125 degree opening, which supports long-term hinge performance when doors are frequently opened. The compact and sturdy design paired with these adjustments provides a concealed hinge setup that can be tuned on site to match the surrounding work.
