Blum Compact 31C hinge is a concealed cabinet hinge for face-frame cabinets that uses a 1-5/16 inch overlay, so the door covers that amount of the frame and gives a consistent layout across a run of doors. The hinge is part of the Blum Compact 31C soft-close BLUMOTION line, providing a concealed solution where the hinge hardware stays hidden when the door is closed, supporting a clean cabinet appearance. BLUMOTION is integrated into the hinge cup, so the soft-close function is built into the hinge body and does not require any separate damper on the cabinet side. A deactivation switch for small or light doors allows the soft-close function to be turned off at the hinge when reduced closing force is preferred on lighter doors. The hinge offers a 110 degree opening angle, which gives wide access into the cabinet interior while keeping the door within a practical swing range for most face-frame layouts.
The hinge uses a dowel design, so the cup side is set into pre-bored holes in the door and secured by the dowel fixation, giving a defined drilling pattern for repeatable production or shop work. A 1/2 inch cup depth is specified, so the door boring depth is known in advance and can be matched to tooling to avoid boring through thinner doors. The hinge offers less minimum reveal by design, which allows tighter gaps between door and frame in suitable layouts, helping create a more continuous cabinet front. Three dimensional cam adjustment lets the installer shift the door up-down, left-right, and in-out at the hinge, so small layout variations in drilling or frame alignment can be corrected using the hinge mechanism instead of reworking the cabinet.
This concealed cabinet hinge is built for face-frame cabinets using a 1-5/16 inch overlay, so it fits projects where the door is designed to cover that portion of the frame and maintain a consistent front across adjacent doors. The 110 degree opening angle works well in standard kitchen and bath cabinet locations, where doors need to open wide enough for access while staying within typical clearances next to walls, appliances, or neighboring cabinets. With a 1/2 inch cup depth, the hinge suits doors that can accept that bore depth without weakening the panel, giving woodshops a clear standard for door preparation. The dowel-style cup configuration lends itself to repetitive drilling with line-boring or CNC equipment, so production runs can keep consistent positioning and speed. As part of the Blum, Inc. concealed cabinet hinges category, this hinge aligns with concealed hardware projects where the hardware remains out of sight when doors are closed.
The Blum Compact 31C soft-close BLUMOTION setup puts the damping mechanism inside the hinge cup, so every door motion is controlled at the pivot point, supporting predictable closing behavior across all doors in the run. Three dimensional cam adjustment on the hinge reduces rework because small differences in cabinet construction or hinge boring can be corrected by turning the cams, allowing each door to be aligned for even reveals without altering the cabinet. The deactivation switch for small or light doors provides flexibility when door sizes vary on a job, since lighter doors can have the soft-close function turned off individually to match how the door mass interacts with the BLUMOTION feature. Less minimum reveal capability lets installers design tighter front gaps within the hinge limits, which helps visually align multiple doors while staying within the range the hinge is designed to handle. Blum's CLIP technology connects the hinge in a repeatable way, so doors can be removed and reattached during finishing or cabinet installation while keeping the setting stable. The overload safety feature inside the hinge addresses occasional over-travel events, supporting continued hinge function in normal cabinet service after unintended forceful opening.
The Blum Compact 31C hinge is classified as a concealed cabinet hinge for face-frame cabinets, so it serves projects where the frame remains visible and the hardware stays hidden.
This hinge is specified for a 1-5/16 inch overlay, meaning the cabinet door is designed to cover that amount of the face frame for consistent reveals.
The hinge provides a 110 degree opening angle, which gives broad cabinet access while keeping the door swing within typical kitchen and bath clearances.
BLUMOTION is integrated into the hinge cup, so the soft-close action operates directly at the hinge and controls the final part of the door closing movement.
The hinge has a deactivation switch for small or light doors, allowing the soft-close function to be disabled on those doors when a freer swing is desired.
The hinge offers three dimensional cam adjustment, so door position can be fine-tuned in multiple directions at the hinge to align gaps and faces.
The Blum Compact 31C hinge with 1-5/16 inch overlay, 110 degree opening angle, and dowel-mounted 1/2 inch cup depth gives a defined standard for face-frame cabinet doors. BLUMOTION integrated into the cup, the deactivation switch for small or light doors, and three dimensional cam adjustment combine into a hinge choice that supports controlled motion and clean alignment. For cabinet projects using concealed face-frame hardware, this hinge configuration provides a repeatable drilling pattern and adjustment range that support consistent doors across the job.
