Blum Compact 31C Soft-Close BLUMOTION 1-3/8" Overlay Face-Frame Hinges Nickel, 107° Screw-On - 31C355B22

Blum Compact 31C Hinge For 1-3/8 Inch Overlay

Blum Compact 31C hinge is a concealed face frame hinge designed for 1-3/8 inch overlay cabinet doors, so it lets you keep a clean exterior while maintaining consistent overlay across a run of face-frame cabinets. As a compact hinge in the concealed cabinet hinges class, it stays out of sight in the interior of the cabinet, which helps deliver a finished look around the opening. The hinge belongs to the Blum Compact 31C soft-close BLUMOTION line, so it controls door closing speed at the hinge cup instead of relying on external devices. As a 107 degree hinge, it opens the door to a wide working angle while still keeping the swing suitable for typical cabinetry layouts. The nickel finish on the hinge presents a uniform appearance inside the cabinet, which supports a professional, consistent interior when multiple hinges are used.

Key Working Details Of This Blum Compact Hinge

• The hinge uses BLUMOTION integrated into the hinge cup, so the soft-close function sits directly at the pivot point and moderates closing movement across everyday door sizes.
• Blum's CLIP technology is utilized on this hinge, which allows the installer to work with a proven Blum connection approach and keep door handling consistent with other CLIP-based projects.
• A deactivation switch for small or light doors is built into the hinge, so the soft-close function can be adapted when less damping is desired on narrower or lighter doors.
• The hinge offers an overload safety feature, which is designed to protect the BLUMOTION mechanism under higher-than-expected closing force and helps maintain function in normal cabinet use.
• Three dimensional cam adjustment is provided on this hinge, so vertical, horizontal, and depth alignment can be tuned at the hinge side to refine reveals after installation.
• The hinge has a 1/2 inch cup depth, giving a defined boring specification in the door that supports repeatable drilling setups across multiple doors.

Screw-On Installation And Cup Boring Details

This Blum, Inc. hinge is described as a screw-on design, so it fastens to the door and face frame using screws rather than press-in components, which suits many shop and site workflows that standardize on screw-attached hardware. The 1/2 inch cup depth listed for this hinge defines the depth of the hinge cup bore in the door, so drilling equipment can be set once and used repeatedly to keep bore depth consistent. With a 1-3/8 inch overlay specification, the hinge is intended to position the door so it overlays the face frame by that amount, giving installers a predictable reference when laying out cabinet faces. Being a concealed cabinet hinge, it mounts within the cabinet interior and door edge, so hinge arms do not project into the room and interfere with access.

How This Concealed Hinge Performs In Cabinet Work

Using The 1-3/8 Inch Overlay Face Frame Hinge

This hinge is identified as a 1-3/8 inch overlay face-frame hinge, so it is suited to face-frame cabinet construction where the door overlays the frame by that dimension, supporting consistent margins along a bank of cabinets. As part of the concealed face frame hinges category, it positions all working parts behind the door and frame, which keeps the front elevation focused on the door style rather than exposed hardware. The 107 degree opening angle allows the door to swing open broadly enough for normal cabinet access while keeping the motion in line with common adjacent-door layouts. With BLUMOTION soft-close integrated into the cup, the damping occurs at the hinge itself, so closing behavior remains consistent from cabinet to cabinet where the same hinge is used. The nickel finish ties into other nickel-finished components in a cabinet interior, helping maintain a unified look whenever doors are opened for use.

Adjustment And BLUMOTION Details For Repeatable Results

The three dimensional cam adjustment built into this hinge lets the installer fine-tune door position in vertical, horizontal, and depth directions at the hinge, which supports tight reveals and alignment without redrilling. This adjustability is especially useful when working with multiple doors across a face frame, because each hinge can be tuned to bring edges into plane. The deactivation switch for small or light doors allows the BLUMOTION function to be adapted when full damping is not required, so narrow or light doors can move in a way that feels appropriate to their size. The overload safety feature is designed around the BLUMOTION system, so the soft-close function is protected when a door is closed with higher force, supporting reliable behavior in day-to-day use. Because BLUMOTION is integrated into the hinge cup, there is no separate soft-close device acting on the door, which keeps the hardware count low while still providing controlled closing.
