Sugatsune HES2S Series 1-1/2" Door Thickness Adjustable Surface Mount Concealed Hinge, Dark Gray, - HES2S-140-A125-DGR

Sugatsune HES2S Concealed Hinge For Thick Doors

Sugatsune HES2S concealed hinge is an adjustable surface mount concealed hinge designed for 1-1/2 inch (38 mm) thick doors, so it supports heavier, thicker panels found in serious woodworking and architectural projects. The hinge is part of the HES2S Series from Sugatsune America, tying it to a known family of invisible hinges that focus on clean, concealed installations. Surface mounting to the door frame allows installation without routing a deep mortise in the frame, helping streamline layout when multiple doors need to be hung. This hinge opens to 125 degrees, giving good access into the cabinet or opening while controlling the door swing. Its compact and sturdy design supports demanding use where a minimal visible profile is important. The dark gray finish helps the hinge blend into shadow lines around the door, keeping attention on the door and frame rather than the hardware.

Key Working Advantages Of This Invisible Hinge

• The surface mount to the door frame simplifies preparation because material only needs to be removed or located at the door side, which can speed up installation on existing frames.
• A minimum door thickness of 1-1/2 inch (38 mm) means the hinge is suited to substantial doors, so it can be matched confidently with thicker cabinet, passage, or panel doors.
• The 125 degree opening angle allows the door to swing wide enough for access while still controlling the arc of travel, which helps when planning nearby walls, cabinets, or trim.
• With two hinges, the rated maximum door weight is 110 lbs, so installers can size hinge count knowing how much load each pair will handle on heavier doors.
• With three hinges, the rated maximum door weight increases to 143 lbs, which supports taller or denser doors where an extra hinge distributes the load more effectively.
• The dark gray finish on this hinge coordinates with darker door edges and frames, which helps maintain a discreet, low-visibility hardware appearance on finished work.

Installation And Adjustment For Precise Door Alignment

This Sugatsune America invisible hinge surface mounts to the door frame, so layout focuses on precise placement rather than deep frame mortising. The hinge offers adjustable depth of plus or minus 1/8 inch (3 mm), which lets installers fine-tune how the door sits in the opening for an even reveal. Vertical adjustment of plus or minus 1/8 inch (3 mm) provides additional control over the gap at the head and sill or cabinet top and bottom, improving alignment between multiple doors. Horizontal adjustment with a spacer of plus or minus 1/16 inch (1 mm) allows small side-to-side corrections to tighten or open clearances, which is especially useful when doors share a common stile or meet at a center line. A door stopper is required to prevent breakage of the hinges and failure of the door, so the hinge is intended to work as part of a controlled-stop door system.

Using This HES2S Hinge In Real Projects

Where The HES2S-140-A125-DGR Hinge Works Best

The HES2S-140-A125-DGR hinge is an invisible hinge in the Invisible and Recessed Hinges category, so it suits projects where concealed hardware is a design priority. Its minimum 1-1/2 inch (38 mm) door thickness rating fits solid wood or laminated doors that carry more weight than thin cabinet fronts, making it appropriate for substantial openings. With a 125 degree opening angle, the hinge supports doors that need to swing wide for access while still working with a separate door stopper that defines the final open position. The stated door weight capacity of 110 lbs with two hinges and 143 lbs with three hinges helps in planning hinge count on taller or wider doors. Because it surface mounts to the door frame, the hinge can be applied in situations where accessing or modifying the frame structure is limited, such as retrofitting into finished carpentry.

Adjustment Range That Supports Repeatable Results

The adjustable depth of plus or minus 1/8 inch (3 mm) allows field tuning of how deeply the door sits relative to the frame, which helps compensate for minor variations in door thickness or framing. Vertical adjustment of plus or minus 1/8 inch (3 mm) gives the ability to shift the door up or down after mounting, supporting consistent reveals across multiple doors on the same run. Horizontal adjustment with a spacer of plus or minus 1/16 inch (1 mm) provides fine control over side gaps, which is valuable when aligning meeting edges or matching adjacent panels. The compact and sturdy design supports this range of adjustment while keeping the hinge body discrete, which helps maintain both function and the clean, concealed look. A door stopper requirement means the hinge is used with a defined stopping point, reducing stress at full open and supporting long-term hinge performance on heavier doors.
