Blum Compact 31C Soft-Close Hinge For Face Frames

Blum Compact 31C soft-close hinge provides a concealed hinge solution for face-frame cabinets with a 1-1/2 inch overlay, so doors cover more frame while keeping the hardware hidden for a clean cabinet appearance on finished jobs. The hinge belongs to Blum's concealed cabinet hinges category, which supports projects where exposed hinges are not desired and consistent reveals matter across multiple doors. Integrated BLUMOTION in the hinge cup controls the soft-close action directly at the hinge, reducing door slamming and helping protect cabinet fronts in everyday use. The hinge offers a 107 degree opening angle, which gives doors generous swing for access while still supporting typical kitchen and bath cabinet layouts. Its nickel finish presents a uniform look inside the cabinet, which is useful when matching other nickel-finished hardware in the same installation.

Key Working Details For Cabinet Installers

• BLUMOTION integrated into the hinge cup manages soft-close performance at the hinge, which helps deliver predictable closing behavior across multiple doors in a run.
• The 1-1/2 inch overlay face-frame design allows the door to cover more of the face frame, supporting layouts that require wider overlay while keeping gaps visually consistent.
• Three dimensional cam adjustment lets the installer fine-tune door position after mounting, which helps correct minor drilling or placement variation without re-boring holes.
• The 1/2 inch cup depth provides a defined boring depth in the door, so drilling setups can be standardized for repeatable hinge cup preparation across a project.
• The 107 degree opening angle supports common cabinet access needs while helping doors clear adjacent faces in many typical face-frame configurations.
• An overload safety feature in the hinge protects the soft-close function under higher loads, which helps maintain hinge performance when doors are used frequently.

Screw-On Mounting And Practical Adjustment

The screw-on configuration of this hinge secures it to the cabinet using screws, giving installers a familiar mounting method for face-frame construction. This style suits shops and field work where screw fastening is already standard practice. Three dimensional cam adjustment built into the hinge allows vertical, horizontal, and depth changes after installation, so doors can be aligned tightly without reworking the cabinet or door. The hinge utilizes Blum's CLIP technology, which provides a defined attachment method between hinge parts, helping streamline mounting and removal during fitting or later adjustments. The 1/2 inch cup depth sets the drilling requirement in the door, which supports jig-based boring processes and consistent hinge positioning across large runs.

Using This Concealed Hinge In Daily Work

Where This 1-1/2 Inch Overlay Hinge Fits

This hinge is designed for face-frame cabinets with a 1-1/2 inch overlay, which suits layouts where the door needs to cover a substantial portion of the frame. In these applications, the overlay specification defines how door edges line up across a bank of cabinets, contributing to straight visual lines. As a concealed cabinet hinge in the concealed face frame hinges category, it suits projects where the client expects hidden hardware and unobstructed exterior profiles. The 107 degree opening angle works well in many kitchen, bath, or utility cabinets, where the door must open wide enough for access but still operate within adjacent walls or cabinets. The nickel finish coordinates with other nickel interior fittings, supporting uniform appearance when the cabinet is open.

How BLUMOTION And Cam Adjustment Support Results

BLUMOTION integrated into the hinge cup delivers soft-close action directly at each hinge, so closing speed and damping are controlled where the door pivots. This design supports quieter operation and helps reduce impact at the cabinet face over repeated use. A deactivation switch for small or light doors allows the soft-close function to be turned off at the hinge, which helps doors of lower weight close fully without excessive resistance. Three dimensional cam adjustment offers fine tuning in three directions, enabling installers to dial in reveals and flushness even when initial drilling varies slightly. The overload safety feature in the hinge protects the soft-close mechanism when doors are moved forcefully, supporting consistent behavior across many open-and-close cycles. Together, these details help reduce rework time during installation and support stable alignment in day-to-day cabinet operation.
