Grass TEC 864 self-close hinge is a concealed cabinet hinge designed for face-frame construction, so doors close quietly while keeping hardware out of sight on finished work. This TEC 864 Series hinge line is made in the USA, which supports consistent manufacturing and predictable performance job after job. As a self-close hinge in the concealed face frame hinges category, it suits professional cabinet installations that need clean lines and dependable door control. The hinge belongs to the concealed cabinet hinges product class, so it works where visible surface hinges are not acceptable. Engineered to exceed industry standards for load rating and opening and closing cycles, the TEC 864 hinge supports demanding use in frequently accessed cabinets. The Grass America brand backing this hinge gives installers a defined product family and part numbering system to match when planning additional cabinets or future work.
The 108 degree hinge in the TEC 864 line provides three dimensional adjustment that helps align doors after installation. A cam side adjustment with plus or minus 1.5 mm movement lets the installer fine-tune the gap between adjacent doors or between door and cabinet side. A cam depth adjustment providing 2.5 mm out and 0.5 mm in travel adjusts the door in and out relative to the face frame, which is useful when doors need to sit flush along a long run. A slotted screw hole height adjustment with plus or minus 2 mm range shifts the door up or down to line up top and bottom reveals. Together these adjustments support accurate margins and help reduce rework when cabinets are slightly out of square or walls are uneven.
The SAP description identifies this hinge as 864VS8 (82-01) SIDE MNT 1/2 inch OL DOWEL, indicating a 1/2 inch overlay side-mount design that suits face frames where the door overlays the frame by that amount. As a face-frame TEC 864 Series hinge, it matches American-style cabinet construction using a front frame instead of full-overlay frameless boxes. The 108 degree opening angle provides wide access to the cabinet interior without over-rotating the door, which helps when cabinets are placed near walls or adjacent units. The doweled cup fastening design described for this version lets the installer use bored dowel holes in the door, which can speed assembly on production runs and help locate the hinge cup consistently. Available boring patterns of 42 mm and 45 mm support different drilling setups, allowing alignment with existing boring equipment or templates during shop work.
The hinge uses a solid metal cup in combination with doweled fastening, so the cup seats positively in the 10.5 mm deep bore and resists shifting under load, which is important when multiple doors must stay aligned over time. All-steel construction in the moving mechanism supports smooth motion across the full 108 degree opening range, which is valuable in high-use cabinets where cycles accumulate quickly. The three dimensional hinge adjustment - side, depth, and height - lets installers correct small drilling or layout variances without refabricating doors or frames, improving workflow on large projects. TEC 864 hinges are available in two cabinet door cup fastening designs, Screw-On and Doweled, so shops can choose either a screw-centered process or a dowel-based process while staying within the same hinge family. The hinge uses #6 x 5/8 inch flat head fasteners for the hinge cup and #8 x 3/4 pan head fasteners for cabinet attachment, which aligns with common cabinet screw sizes already used in many shops.
The Grass TEC 864 self-close hinge is designed to work with doors up to 3/4 inch thick, which matches standard cabinet door stock used in many face-frame cabinet projects.
The TEC 864 concealed cabinet hinge opens to 108 degrees, giving wide access to cabinet interiors while limiting over-rotation around nearby walls or adjacent cabinets.
The TEC 864 hinge offers plus or minus 1.5 mm side adjustment, 2.5 mm out and 0.5 mm in depth adjustment, and plus or minus 2 mm height adjustment for fine-tuning reveals.
The TEC hinge shallow 10.5 mm cup accommodates most profiled door edges, so decorative edge routing can be used without cutting too deeply into the door.
The SAP description 864VS8 (82-01) SIDE MNT 1/2 inch OL DOWEL identifies this TEC 864 hinge as a 1/2 inch overlay side-mount design for face-frame cabinets.
The TEC 864 hinge uses #6 x 5/8 inch flat head fasteners for the hinge cup and #8 x 3/4 pan head fasteners for cabinet mounting, matching common cabinet screw sizes.
This Grass 02871-15 hinge combines a 1/2 inch overlay side-mount layout with a shallow 10.5 mm cup, so it aligns well with face-frame cabinets using profiled 3/4 inch doors. The TEC 864 three dimensional adjustment and all-steel mechanism support precise reveals and durable motion on active doors. When a project calls for a concealed self-close solution from a defined hinge family, this TEC 864 self-close hinge offers a clear, part-numbered option that fits common boring patterns and standard cabinet fasteners.
