Description
Grass TEC 864 Hinge For 3/4 Inch Overlay Doors
Grass TEC 864 hinge is a concealed cabinet hinge from Grass America that is built as a self-close, 3/4 inch overlay face-frame solution, so it lets you hang typical cabinet doors while keeping hardware hidden from the front. The hinge is part of the TEC 864 Series made in the USA and engineered to exceed industry standards for load rating and opening and closing cycles, which supports demanding cabinet use in busy environments. With a 108 degree opening angle, the hinge allows doors up to 3/4 inch thick to open wide enough for access while staying within the working swing of most face-frame layouts. The hinge belongs to the concealed face frame hinges class, so it is designed around face-frame construction rather than frameless applications. A solid metal cup with all moving mechanism parts in all-steel construction gives the hinge a metal-on-metal working core, which supports long-term function during repeated cycles.
Key TEC 864 Details That Support Cabinet Work
- The TEC 864 hinge uses a shallow 10.5 mm cup depth, about 13/32 inch, so it can work with many profiled door edges without cutting deeply into the panel and helps maintain material strength around the cup.
- Three-dimensional adjustment on the 108 degree TEC 864 hinge provides cam side adjustment of plus or minus 1.5 mm, allowing fine left-right alignment of the door to tighten reveals across a run.
- Cam depth adjustment on the hinge offers 2.5 mm out and 0.5 mm in movement, so the door position to the face frame can be tuned after mounting instead of relying only on initial drilling accuracy.
- Slotted screw hole height adjustment of plus or minus 2 mm lets the door move up or down on the face frame, which helps compensate for drilling variation and achieve consistent top and bottom gaps.
- The hinge can be ordered in screw-on cabinet door cup fastening design, giving installers a familiar method for securing the metal cup in drilled bores on the door.
- Available boring patterns of 42 mm and 45 mm on the TEC hinge line match common drilling setups, which supports use with standard hinge-boring equipment in a cabinet or shop setting.
Installation Details For Face-Frame TEC 864 Hinges
The 108 degree TEC 864 hinge is configured as a concealed face-frame hinge, so it is aimed at cabinets built with a face frame rather than flush, frameless sides. TEC 864 hinges provide two cabinet mounting options, side mount and wraparound mount, giving flexibility in how the hinge base attaches to the frame. The wraparound mount style is designed to seat on 3/4 inch thick face frames by positively locating the hinge base on the face frame, which helps stabilize positioning when attaching to standard framed cabinets. The side mount option supports mounting the hinge base flat to the face of the frame, giving an alternative layout that can match existing shop preferences. The screw-on fastening design for the cup uses standard screw attachment into the door, aligning with typical shop drilling and assembly steps.
How This Grass TEC 864 Hinge Performs In Use
Face-Frame Cabinet Use And Mounting Options
The Grass TEC 864 self-close hinge is part of a concealed cabinet hinge family for face-frame cabinets, so it suits installations where the frame remains visible while the hinge stays hidden behind the door. With a 3/4 inch overlay specification, the hinge is designed for doors that cover most of the face frame while still leaving a small reveal, which matches many kitchen and built-in cabinet layouts. The TEC 864 hinge offers side mount and wraparound mount cabinet mounting options, so shops can match the base style to existing drilling patterns or production standards. Wraparound mount bases locate on 3/4 inch thick face frames, helping position the hinge accurately along the frame edge during installation. Side mount bases fasten directly to the frame face, supporting straightforward alignment along a layout line. Being made in the USA and engineered to exceed industry standards for load rating and opening and closing cycles, the TEC 864 hinge is suited to cabinets that see repeated daily use, such as kitchens, baths, and storage areas.
Adjustment Range, Cup Design, And Workflow Impact
The TEC 864 hinge provides three-dimensional adjustment that directly supports installation workflow and final fit. Cam side adjustment of plus or minus 1.5 mm lets installers shift the door sideways without redrilling, which is useful for aligning reveals across multiple doors. Cam depth adjustment with 2.5 mm out and 0.5 mm in travel allows the door to move toward or away from the face frame, helping correct minor drilling offsets or door warp with a simple screwdriver adjustment. Slotted screw hole height adjustment of plus or minus 2 mm gives vertical play, which helps level door tops and bottoms on a face frame after the hinges are fastened. The hinge uses a shallow 10.5 mm metal cup, about 13/32 inch deep, so it works with many profiled door edges without cutting too deeply into the stile, helping maintain integrity of thinner or molded doors. All moving mechanism parts are constructed in all steel within a solid metal cup, which supports consistent motion during repeated opening and closing cycles. A 108 degree opening angle gives wide access into the cabinet while keeping the swing range suitable for typical cabinet runs. Available boring patterns of 42 mm and 45 mm fit common hinge boring machines, which streamlines shop setup and reduces changeover time when drilling doors for this hinge.
