Invisible Hinges 3-1/2 x 1 describe this Peter Meier, Inc. 2015 Series hinge as a compact, recessed hinge that stays out of sight, so doors or panels close cleanly while the hardware remains hidden in the workpiece. The invisible hinge design ties directly to invisible and recessed hinge applications, allowing the hinge to sit inside the material and keep exterior faces uninterrupted on cabinets or architectural panels. The stated 3-1/2 inch by 1 inch size gives a clear reference for layout, so you can plan mortise dimensions and edge clearances around a known hinge footprint. Being part of the Invisible Hinges product class aligns it with projects that call for concealed pivot points rather than traditional surface-mounted hinges, which helps when matching appearance standards across a job.
The stated 3-1/2 inch by 1 inch body of this Peter Meier, Inc. invisible hinge sets the primary footprint you work around, so mortises in doors and frames can be sized reliably for snug, repeatable fit. Its placement under Hinges | Invisible and Recessed Hinges defines the intended installation method as recessed into the material, which means hinge pockets can be integrated into machining sequences on cabinet doors, jambs, or panels. The Invisible Hinges product class also signals that alignment happens inside the workpiece, helping maintain consistent gaps and smooth operation without exposed hinge knuckles. The 2015 Series naming gives a stable identifier, which is useful when standardizing hinge type across multiple openings in a build.
The SAP description "INVISIBLE HINGE 89X25 BRONZE STEEL/NYLON" identifies this part as a bronze-colored steel and nylon invisible hinge, so it suits applications where the hardware body sits hidden yet still benefits from a metal-and-nylon construction inside the mortise. The web description calling it "Nylon, 3-1/2 x 1" reinforces the nylon component in the hinge makeup, which matters for projects that value a combination of metal strength and nylon contact or movement surfaces within a compact hinge body. Being categorized specifically as an Invisible Hinge and part of the 2015 Series points it toward cabinet, furniture, or panel work where the design goals call for concealed hinges rather than exposed butt hinges, helping the hinge support uninterrupted surfaces on doors and frames. Its Peter Meier, Inc. branding connects it into a recognized hinge line within the woodworking trade.
The repeated identification as a 2015 Series invisible hinge gives installers a precise series reference, which matters when repeating hinge selection across multiple rooms, cabinet runs, or future additions that must match earlier work. The 3-1/2 inch x 1 inch callout provides a fixed size standard, so jigs, templates, or CNC programs can be built around that footprint and used again without reworking dimensions from job to job. The mention of 89x25 together with 3-1/2 x 1 ties imperial and metric-style sizing to the same hinge, which helps coordinate between metric shop drawings and inch-based tools in the field. Classification under Hinges | Invisible and Recessed Hinges confirms the hinge operates inside routed or bored pockets, supporting clean sightlines and allowing door reveals to be controlled without exposed hinge barrels. The bronze steel and nylon description provides a clear material mix, informing expectations about how the hinge body presents visually at the mortise edges and how internal elements contribute to the overall movement inside the concealed installation.
The hinge is identified as Manufacturer Part # C2015BBR and listed as 2015 Series, so it aligns with that specific invisible hinge family when matching parts on a project.
The hinge is described as 3-1/2 inch x 1 inch, giving a clear body size for planning mortises, edge setbacks, and alignment with door and frame thickness.
The product sits in the Hinges | Invisible and Recessed Hinges category, indicating it is intended to be recessed and concealed inside the material rather than surface-mounted.
The SAP description notes bronze steel and nylon, and the web description notes nylon, so the hinge combines steel and nylon elements in a bronze-colored hinge body.
The 89x25 dimension in the SAP description corresponds with the 3-1/2 x 1 inch size, helping align metric-style design notes with inch-based mortising on site.
The Invisible Hinges product class and recessed hinge category position it for concealed hinge applications in cabinets or panels where visible hinge leaves are not desired.
This Invisible Hinges, 3-1/2 inch x 1 inch 2015 Series, Nylon Bronze Steel hinge from Peter Meier, Inc. pairs a defined size with a concealed, recessed hinge style, so projects needing hidden hinge points can be laid out around known 3-1/2 x 1 mortises. The bronze steel and nylon description characterizes the hinge construction, supporting expectations about materials interacting within the hinge body. With the C2015BBR part number and 2015 Series designation, it fits workflows that standardize on a specific invisible hinge series for cabinetry, furniture, or panel systems available through Wurth Baer Supply.
