Blum Compact 31C soft close hinge is a concealed cabinet hinge designed for 1-1/4 inch overlay face-frame doors, so it lets you build a clean front appearance while using a practical overlay size common in framed cabinetry. The hinge belongs to Blum's Compact 31C series, which keeps the mechanism tight to the frame and useful where interior space matters. Nickel finish on the hinge provides a neutral, project-friendly appearance that coordinates with typical cabinet interiors. A 110 degree opening angle gives doors wide swing without being excessive, helping doors clear adjacent surfaces in many standard layouts. This hinge is part of the concealed cabinet hinges class, so all working parts stay hidden when the door is closed, supporting a finished look on visible runs. The design supports soft-close BLUMOTION action, so door closing is controlled at the hinge rather than relying on external devices.
This hinge uses a screw-on mounting style, so it fastens directly with wood screws and suits projects where installers prefer mechanical attachment over press-in methods. The 1/2 inch cup depth on the hinge sets the drilling depth into the door, which matters when working with thinner doors or veneered panels. The hinge is designed for 1-1/4 inch overlay on face-frame cabinets, so the door covers that amount of frame and can be planned into rail and stile dimensions. The 110 degree opening angle controls how far the door swings, which helps coordinate layouts where doors meet walls, appliances, or other cabinets in a run.
This hinge is specified as a 1-1/4 inch overlay face-frame hinge, so it is intended for framed cabinets where the door overlays the face frame by that amount on the hinge side. In practice, this overlay lets you use a generous door size while still referencing off a predictable frame edge. As a concealed cabinet hinge, it sits inside the case so the external appearance stays focused on the door design. The 110 degree opening angle gives adequate access into the cabinet interior while limiting how far the door projects into nearby traffic paths. Nickel finish on the hinge offers a neutral interior look that suits both shop-built and factory-style casework. The hinge belongs to Blum's Compact 31C family, keeping the hardware footprint contained and appropriate for many kitchen, bath, or utility cabinet layouts where interior space is planned closely.
The three dimensional cam adjustment on this hinge provides built-in fine-tuning of door position, which lets installers correct minor drilling variances and align multiple doors without altering mounting points. Because BLUMOTION is integrated into the hinge cup, soft-close control occurs exactly where the door pivots, giving a consistent closing action from full open through final contact. The overload safety feature serves the BLUMOTION unit by absorbing excess closing force, which is useful in busy spaces where doors are pushed firmly. A deactivation switch for small or light doors on the hinge gives control over damping behavior, so light fronts can close without excessive resistance while heavier doors retain the full soft-close effect. The screw-on mounting design keeps installation straightforward for those used to traditional wood screw fastening, supporting repeatable results across production runs or retrofit work.
