Grass TEC 864 hinge is a concealed cabinet hinge for face-frame construction that delivers a self-close action for controlled door closing on everyday use cabinets. Made in the USA, this TEC 864 Series hinge is engineered to exceed industry standards for load rating, opening, and closing cycles, so it supports demanding residential or light commercial cabinet duty. The hinge is part of the concealed face frame hinge class, keeping hardware out of sight while the door operates on a precise metal mechanism. A 108 degree opening angle lets the door swing wide enough for comfortable access to cabinet interiors. This specific version is a screw-on design, so the hinge cup fastens to the door using screws for a secure mechanical connection that supports repeatable installations across multiple doors on a job.
The TEC 864 hinge uses a shallow 10.5 mm (13/32 inch) cup depth, which works with most profiled door edges so door preparation can stay within common boring depths on raised or shaped doors. TEC 864 hinges offer two cabinet mounting options, side mount and wraparound mount, allowing face-frame cabinet builders to match the hinge support style to their frame design. The wraparound mount style mounts on 3/4 inch thick face frames by positively locating the hinge base on the face frame, which helps position the hinge consistently from cabinet to cabinet. The hinge cup fastens using a screw-on design, so doors are attached with screws for direct mechanical retention while drilling patterns follow available 42 mm and 45 mm boring layouts.
This Grass America concealed cabinet hinge is designed specifically for face-frame cabinets that use 3/4 inch thick face frames, so it ties directly into common North American cabinet construction. The wraparound mount version locates on the 3/4 inch face frame, giving a positive reference point when positioning the hinge base in production or on retrofit work. A 3/4 inch overlay configuration matches doors that overlay the face frame by 3/4 inch, so the hinge geometry supports that overlay relationship once the boring pattern and mounting position are followed. The hinge is designed to work with doors up to 3/4 inch thick, so standard cabinet door thicknesses fall within its operating range without overloading the concealed mechanism. As a concealed face frame hinge in the TEC 864 Series, it suits jobs where visible surface hinges are not desired and a clean cabinet exterior is preferred.
The 108 degree TEC 864 hinge offers three-dimensional adjustment, which supports fine-tuning door alignment after mounting. A cam side adjustment of plus or minus 1.5 mm shifts the door sideways on the hinge, helping align reveals across a run of cabinets. A cam depth adjustment that moves 2.5 mm out and 0.5 mm in lets the installer move the door closer to or farther from the cabinet, so the door face can be aligned with adjacent fronts or trim. A slotted screw hole height adjustment of plus or minus 2 mm changes the vertical position, permitting on-cabinet tuning of top and bottom gaps without redrilling. The hinge is available with 42 mm and 45 mm boring patterns, giving flexibility to match existing shop drilling setups. The hinge cup fastens to the door with screw-on fastening, and the product uses #6 x 5/8 inch flat head screws for the hinge cup and #8 x 3/4 inch pan head screws on the cabinet side, creating a defined screw specification when planning drilling, tooling, and hardware pulls for a project.
The Grass TEC 864 hinge is designed for face-frame cabinets, so it works within traditional framed construction where a face frame defines the cabinet front.
The 3/4 inch overlay configuration means the door overlays the face frame by 3/4 inch, so door sizing and hinge location are based on that overlay dimension.
The 108 degree TEC 864 hinge is designed to work with doors up to 3/4 inch thick, so standard cabinet doors in that range remain compatible with the hinge geometry.
The 10.5 mm (13/32 inch) shallow cup depth allows hinge boring on most profiled or shaped door edges without cutting excessively deep into the panel.
The TEC 864 hinge offers side mount and wraparound mount options, so the cabinet side connection can match the face-frame design and shop preference.
The TEC 864 hinge uses #6 x 5/8 inch flat head screws for the hinge cup and #8 x 3/4 inch pan head screws for the cabinet side connection.
This Grass TEC 864 hinge combines 3/4 inch overlay geometry, face-frame wrap capability, and three-dimensional adjustment, so it fits projects that need concealed hinges tuned for framed cabinets. With a shallow 10.5 mm cup, 108 degree opening, and self-close function, the hinge supports accessible cabinets with smooth closing motion. Defined screw sizes, 42 mm and 45 mm boring patterns, and solid metal cup construction align this hinge with production cabinet workflows where consistent drilling and mounting are critical. For work built around 3/4 inch thick face frames and doors up to 3/4 inch thick, this TEC 864 configuration from Grass America provides a concealed hinge solution ready for repeatable, accurate cabinet installations.
