Pro Value Series free swinging overlay hinge gives you a semi-concealed institutional hinge that suits overlay doors where a clean exterior and exposed knuckle are both important. The hinge is classed as a semi-concealed hinge, so part of the leaf is hidden while the five knuckle barrel remains visible, which helps match typical institutional and commercial cabinet lines. The hinge is described as free swinging, meaning it operates without a built-in self-closing spring, which suits applications where the door is controlled by other hardware or user operation. The black overlay description ties the black finish to overlay door layouts, helping you match dark hardware schemes on institutional casework or cabinetry. As part of the Hinges and Institutional Hinges category, this hinge is intended for heavier-use environments instead of light residential furniture.
This black overlay institutional hinge is described as screw-on, so it mounts using screws rather than press-in or weld-on attachment, which suits field work on wood casework. The hinge is designed for a 32 mm hole pattern, tying directly into line-bored cabinet sides where that system drilling is already in place. The recommended screws are #8 x 3/4 inch, so matching that shank and length provides full thread bite through typical hinge leaves into cabinet material. The hinge is intended for a 3/4 inch door thickness, aligning door edge geometry and screw length with standard cabinet doors. With a 2-3/4 inch joint length in a five knuckle layout, the pivot point ends up correctly positioned for overlay doors, helping the door clear the cabinet while keeping the knuckle line straight.
This Pro Value Series free swinging overlay hinge, identified as PROIH74-BL, is positioned in the Institutional Hinges product class, so it is oriented toward institutional cabinets, lockers, and casework rather than decorative furniture. The hinge is semi-concealed, meaning part of the hardware hides inside the cabinet while the five knuckle joint remains visible, fitting projects that need an institutional look with some hardware covered. The hinge works with 3/4 inch thick doors, which is a common specification for commercial-grade cabinet doors and millwork, so it fits standard door builds used in many shops. Being designed around a 32 mm hole pattern, it slots into cabinets laid out with system 32 line boring, letting you carry that drilling standard across carcasses and hinges without layout changes.
The hinge is BHMA/ANSI tested Grade 1, which indicates it has been tested to a high performance standard for institutional hinges and supports use where doors see frequent operation. The 0.095 inch steel leaf thickness contributes to that Grade 1 rating by giving more bearing surface and stiffness at the joint, helping the hinge resist deformation over time on heavy-use doors. Its five knuckle configuration distributes load along multiple knuckles, which helps the 4.8 mm pin share stress and maintain smoother swing under repeated cycling. The hospital tip on the pin closes off the end with a rounded profile, which is often preferred on institutional projects that specify hinge tips without exposed sharp corners. When paired with the recommended #8 x 3/4 inch screws, the screw-on design lets installers anchor the hinge solidly to both door and frame members in wood casework. The black overlay description ties the hinge to dark finish hardware schemes where visible knuckles and leaf edges need to sit visually with other black components.
The hinge is designed for a 32 mm hole pattern, so it aligns with system 32 line-bored cabinet sides often used in institutional and commercial casework layouts.
The PROIH74-BL hinge is intended for 3/4 inch door thickness, aligning its overlay geometry and screw engagement with common cabinet door construction.
The 2-3/4 inch joint length five knuckle hinge provides a familiar barrel layout, giving stable pivot geometry and a consistent sight line along multiple doors.
The BHMA ANSI Grade 1 rating indicates the hinge has been tested as a high-grade institutional hinge, supporting frequent door use in demanding environments.
The hinge recommends #8 x 3/4 inch screws, so mounting with that size gives appropriate thread length through the 0.095 inch steel leaves into typical cabinet substrates.
The 4.8 mm pin with hospital tip provides a robust pivot while the rounded tip profile suits institutional environments that favor smooth, closed hinge ends.
This Pro Value Series free swinging overlay hinge, PROIH74-BL, combines a semi-concealed layout with a black overlay finish, aligning with institutional projects that use dark hardware. The hinge is designed for 3/4 inch doors and a 32 mm hole pattern, fitting standard system 32 casework found in many facilities. Its BHMA/ANSI Grade 1 tested status, 0.095 inch steel construction, and five knuckle, hospital tip pin layout all support frequent-use cabinet doors. For institutional overlay door runs that call for a black, screw-on hinge built around these dimensions, this model provides a focused match.
