Grass TEC 864 Self-Close 1-3/8" Overlay Face-Frame Hinges Nickel, 108° Dowel - 02898-15

Grass TEC 864 Hinge For Face Frame Doors

Grass TEC 864 hinge defines a concealed face frame hinge for 1-3/8 inch overlay cabinet doors where a clean exterior is important. This TEC 864 self-close hinge works as a concealed cabinet hinge, keeping hardware hidden while controlling the door swing to 108 degrees for access during everyday use and installation work.

The TEC 864 Series hinge line is made in the USA, which gives shops and installers a consistent source for repeat projects using the same geometry and motion. Its solid metal cup and all-steel moving mechanism parts handle regular opening and closing cycles in kitchen, bath, or shop cabinets where hinges see steady use.

This Grass America hinge belongs to the concealed cabinet hinges class, so it sits inside the 10.5 mm (13/32 inch) cup bored in the door, supporting most profiled door edges while keeping the exterior uncluttered. As part of the TEC 864 family, it is designed to work with doors up to 3/4 inch thick, aligning with common cabinet door construction.

The hinge is offered in a nickel finish, so it presents a neutral, professional look in the case interior that pairs with typical drawer slides and other nickel-plated hardware. A 1-3/8 inch overlay layout fits many face frame designs where a larger overlay is needed, helping cover frame gaps and simplifying layout for runs of cabinets using the same overlay dimension.

Key TEC 864 Details That Support Installers

• The TEC 864 Series hinge line is made in the USA, so dimensions and action stay consistent from job to job, which helps when repeating a drilling pattern across a full kitchen or commercial run.
• All TEC 864 hinges feature a solid metal cup, giving the hinge body a stable base in the door, which matters when doors are opened and closed through many cycles over the life of the cabinet.
• All moving mechanism parts have all-steel construction, so the working joints resist deformation under regular use, supporting long-term alignment of overlay and reveals in typical cabinet installations.
• 108 degree TEC 864 hinges are designed to work with doors up to 3/4 inch thick, matching standard cabinet door builds and allowing predictable clearances without changing hinge families.
• TEC hinges have a shallow 10.5 mm (13/32 inch) cup, which helps when boring near profiled door edges, reducing the risk of breaking through thinner decorative profiles during machining.
• TEC 864 hinges have two cabinet mounting options, side mount and wraparound mount, giving layout flexibility when choosing how the hinge meets a 3/4 inch thick face frame.

Installation And Adjustment Details For TEC 864

The Grass TEC 864 side mount hinge uses a face frame mounting geometry suited to 1-3/8 inch overlay layouts, so once the frame position is established the overlay dimension repeats cleanly across multiple doors. The 108 degree opening angle keeps the door clear enough for access while still controlling how far the door projects into surrounding spaces.

For the door side, the hinge uses a shallow 10.5 mm cup bored into the door, which helps when working with doors that have profiled or shaped edges, since there is more material left between the bore bottom and the outer profile. Available boring patterns of 42 mm and 45 mm support different shop setups while keeping within the TEC 864 system.

The TEC 864 108 degree hinge has three dimensional adjustment, which lets the installer tune the door planes after mounting. Cam side adjustment of plus or minus 1.5 mm shifts the door sideways relative to the frame, helpful for dialing in reveals between doors or at end panels.

Cam depth adjustment of 2.5 mm out and 0.5 mm in changes how the door sits in relation to the cabinet front, which matters when aligning a run of doors flush along a face frame. A slotted screw hole height adjustment of plus or minus 2 mm gives vertical play, so the top and bottom gaps at each door can be matched in the field.

Using The TEC 864 Hinge In Cabinet Runs

Where This 1-3/8 Overlay Hinge Fits Best

This Grass concealed face frame hinge is aimed at cabinets using 1-3/8 inch overlay doors on face frames, so it fits projects where the door is intended to cover more of the frame. That larger overlay can reduce visible frame lines, which some designs prefer, and can hide small layout variations in the frame.

The wraparound mount style option within the TEC 864 line mounts on 3/4 inch thick face frames by positively locating the hinge base on the face frame, which provides a repeatable reference during installation. That positive location helps keep overlay consistent door to door, important when lining up multiple cabinets in a run.

Available boring patterns of 42 mm and 45 mm on TEC hinges serve different drilling fixtures while still staying inside the TEC 864 geometry, so a shop can match existing jig spacing without changing the basic hinge style. The nickel finish suits interiors where other hardware uses similar tones, creating a unified look when the door is open.

The hinge is part of Grass America concealed cabinet hinges, so it is designed for interior positioning with the solid metal cup and all-steel mechanism sitting in the bored door cavity. This arrangement removes external hinge knuckles from the face frame, creating a clear front surface that can be trimmed, finished, or cleaned without working around exposed hinge leaves.

Why TEC 864 Adjustment And Construction Matter

The three dimensional hinge adjustment built into the 108 degree TEC 864 hinge helps reduce rework when aligning multiple doors. Cam side adjustment allows fine tuning of the overlay, so doors can be brought into line even if the frame or door edges vary slightly from nominal dimensions.

Depth adjustment of 2.5 mm out and 0.5 mm in lets the installer refine how the door sits against the face frame plane. This becomes valuable when scribing face frames or when a run of cabinets meets uneven walls, because small adjustments at each hinge can bring the door faces into a more uniform plane.

The plus or minus 2 mm height adjustment provided by the slotted screw hole affects how the top and bottom gaps appear across a bank of doors. Being able to shift the door vertically in this window allows matching reveals without re-boring hinge cups or altering the face frame edge.

All-steel construction of the moving mechanism parts supports that adjustment over time because the joints are built from steel, so the set positions are designed to remain stable through the opening and closing cycles described in the TEC 864 engineering standards. The solid metal cup reinforces the connection to the door material, spreading loads over the bored area.

The hinge design is described as engineered to exceed industry standards for load rating and opening and closing cycles, indicating it is created to operate through demanding cabinet use where doors are opened many times per day. In such environments, having a hinge with this engineering intent can support long-term alignment.

As part of the TEC 864 series, the hinge fits within a known system of geometry, cup depth, and adjustment, which helps when shops standardize boring and setup processes. Using a single hinge family for many cabinets streamlines drilling fixtures, training, and on-site adjustment steps based on the same adjustment ranges.
