Sugatsune free swinging overlay glass door hinge defines this GH-456N/SN hinge as a screw-on, satin nickel unit for overlay glass doors, so installers can plan it as a dedicated glass showcase hinge rather than adapting a generic cabinet hinge. The hinge is suitable for showcases, which positions it well for display cabinets where clear door swing and presentation matter. Its free swinging function means the hinge allows movement without an integrated catch, so door motion can be managed by separate hardware or the case design. The wrap angle glass door hinge construction supports overlay use, which lets the glass door cover the front of the cabinet opening instead of sitting inset. This overlay setup helps align doors with surrounding panels on display runs. The satin nickel finish provides a neutral, project-friendly appearance that coordinates with many commercial and residential showcase designs.
The hinge is a screw-on satin nickel design, which gives installers a familiar fastening method when fixing it to the case structure. Vertical mounting adjustment of plus or minus 1 mm helps correct minor drilling layout variations without redrilling, saving time on site. Horizontal adjustment of plus or minus 1.2 mm lets the door be shifted closer or farther from the case side, refining the gap line after the glass is hung. The spacer arrangement accommodates glass thickness from 5-8 mm, so the hinge can hold glass consistently without changing the basic hardware for each thickness. Using different spacer counts for 3/16 inch, 1/4 inch, and 5/16 inch glass allows the clamping geometry to stay consistent across those sizes. This adjustment range and spacer approach work together to support precise door alignment on glass showcases.
The hinge is described as suitable for showcases, directing it toward display cabinets in retail, residential, or commercial environments where glass fronts are required. Its overlay use means the glass door covers the cabinet opening, supporting designs where the case interior needs a full opening without inset face interference. The applicable glass door size per pair is specified as 600 mm, or 23-5/8 inch, in width, which defines the intended door span per hinge pair so planners can size doors within that envelope. The applicable door height per pair is 1,200 mm, or 47-1/4 inch, which sets a practical limit on tall doors supported by a pair of hinges. The applicable door weight per pair is 15 kg, or 33 lb, giving a clear load reference when choosing glass thickness and door dimensions within the 5-8 mm range. These combined door width, height, and weight figures help establish the hinge in medium-size showcase door applications where stable swing is expected.
The mounting position adjustability of plus or minus 1 mm vertically and plus or minus 1.2 mm horizontally allows installed doors to be fine-tuned so reveals stay consistent along the run. This capability is especially useful on showcase installations where multiple glass doors share the same face line, and small drilling variations could otherwise produce visible misalignment. The spacer-based accommodation of 5-8 mm glass thickness keeps the hinge geometry aligned with the glass edge, supporting even clamping on 3/16 inch, 1/4 inch, and 5/16 inch glass. For 3/16 inch glass, the setup uses 3 spacers, which fills the gap so the hinge interfaces properly with thinner material. For 1/4 inch glass, the use of 2 spacers adjusts the pocket for that intermediate thickness. For 5/16 inch glass, no spacer is required, which indicates the hinge body is dimensioned for that thickness directly. By defining these spacer arrangements, the hinge supports repeatable installation outcomes on showcases using any of the specified glass sizes.
The hinge is for overlay use on glass doors, so it is intended for doors that overlap the cabinet opening rather than sit inset within the frame.
The hinge accommodates 5-8 mm glass thickness, so it can support common 3/16 inch, 1/4 inch, and 5/16 inch showcase glass on the same project line.
A pair is applicable for doors up to 600 mm wide, 1,200 mm high, and 15 kg weight, guiding door layout for stable operation on showcases.
The mounting position adjustability of plus or minus 1 mm vertically and plus or minus 1.2 mm horizontally lets installers align reveals without relocating hinge positions.
The hinge is suitable for showcases because it supports overlay glass doors within specified size and weight limits, matching typical glass display cabinet requirements.
The hinge is a satin nickel design, giving a neutral metal finish that coordinates with many showcase frames and interior hardware selections.
The Sugatsune free swinging overlay glass door hinge GH-456N/SN offers screw-on mounting, overlay use, and adjustment ranges that support accurate alignment on glass showcases. Its applicability to doors up to 600 mm wide, 1,200 mm high, and 15 kg weight per pair defines a clear working envelope for planning door size and glass thickness within the 5-8 mm range. The specified spacer arrangements for 3/16 inch, 1/4 inch, and 5/16 inch glass give a straightforward path to matching the hinge to the door material. For showcase projects calling for satin nickel glass door hinges with defined adjustment and size parameters, this hinge provides a focused option ready to integrate into display cabinet layouts.
