Sugatsune HES2S concealed hinge is an adjustable surface mount concealed hinge designed for 1-3/8 inch (35 mm) minimum door thickness, so it supports solid interior doors where a hidden hinge look is required. This hinge surface mounts to the door frame, which simplifies installation on existing frames and avoids deep mortising in the jamb. It belongs to the invisible hinges class, so the hardware stays out of sight when the door is closed, supporting clean architectural lines on finished work. The hinge offers a maximum opening angle of 110 degrees, which provides a wide, practical swing range for everyday passage while keeping the hinge within its designed motion. Center mounting the hinge on a 1-3/8 inch door allows the door to function as either right-handed or left-handed, which helps standardize prep work across openings.
Surface mounting to the door frame allows the Sugatsune HES2S concealed hinge to be installed directly on the jamb face, which streamlines layout on renovation or new work using standard carpentry tools. The hinge offers 3D adjustment - vertical, horizontal, and depth - so the door position can be tuned after hanging to close gaps, align reveals, and pull the door flush with the frame. The warm gray finish provides a neutral appearance around the hinge area, which blends with many frame finishes when the door is open. A maximum opening angle of 110 degrees keeps motion within a controlled arc, so the hinge operates within its designed travel during daily use.
The Sugatsune HES2S Series 1-3/8 inch door thickness adjustable surface mount concealed hinge is intended for doors using a minimum thickness of 1-3/8 inch (35 mm), so it suits many interior and architectural doors built from that stock. As an invisible hinge class product, it is used where a concealed hardware appearance is desired, letting the door and frame lines remain uninterrupted when closed. Center mounting the hinge on a 1-3/8 inch door allows the same prep to serve right-handed or left-handed operation, which helps streamline door production runs and on-site hanging across a project. With a maximum door weight rating of 88 lbs when using two hinges, it supports medium-weight doors in pairs, while the 110 lbs rating with three hinges supports heavier or taller doors by distributing load across an additional hinge. The warm gray color identified on the HES2S-150-A110-WGR model offers a subdued tone when the hinge is exposed in the open position.
The 3D adjustment capability on this Sugatsune concealed hinge provides vertical, horizontal, and depth tuning, so the installer can shift the door up or down, side to side, and in or out relative to the frame after fastening. This helps correct small drilling variances and frame irregularities, giving control over uniform reveals and smooth latching without extensive rework. The maximum opening angle of 110 degrees defines how far the door can swing, which guides placement relative to adjacent walls, cabinets, or trims to avoid interference in everyday operation. Surface mounting to the door frame keeps all hinge work at accessible faces, supporting clear layout marks and easier adjustments with the door hung. By matching the number of hinges to the stated weight limits - two hinges for doors up to 88 lbs or three hinges up to 110 lbs - the door load is kept within the hinge design range, which supports consistent movement under normal use.
