Blum Compact 30C hinge is a concealed face frame hinge designed for 5/16 inch overlay doors, so the door covers a controlled amount of the face frame while keeping the hardware hidden from the front. The hinge belongs to Blum's Compact 30C line of concealed cabinet hinges, which keeps the cabinet front clean while still allowing access for adjustment at the hinge side. A 105 degree opening angle on this hinge provides wide door swing for cabinet access while staying within a range commonly used on face frame kitchen and bath cabinets. The hinge is specified with a dowel version, giving an installer a defined mounting method when working with pre-bored doors that accept dowel-style hinge mounting. This model is finished in nickel, providing a uniform metal appearance that matches other nickel-finished cabinet hardware in the same installation.
This concealed cabinet hinge is categorized as a concealed face frame hinge, so it is intended for use on cabinets built with a face frame rather than frameless construction. The 5/16 inch overlay detail describes how far the door overlays the face frame edge, so a layout using this hinge can be planned and repeated across multiple openings. The dowel version of this Blum Compact 30C soft-close BLUMOTION 5/16 inch overlay hinge uses dowels in the hinge cup area, so it suits door preparation that is bored for dowel insertion rather than screw-only cup attachment. With the hinge hidden when the door is closed, the visible cabinet design can focus on door style while the hinge manages movement behind the scenes.
The Blum Compact 30C soft-close BLUMOTION 5/16 inch overlay face-frame hinge applies to cabinets that combine a face frame front with overlay doors, so it supports common kitchen, bath, and utility cabinet layouts that follow this construction style. As a concealed cabinet hinge, it mounts inside the cabinet, keeping the nickel hinge out of sight from the room side while still providing a consistent metal finish inside the cabinet. The 105 degree opening angle allows the door to swing outward far enough for normal access to shelves and stored items, so users can load and unload cabinets without the limited reach of smaller opening angles. The 7/16 inch cup depth and dowel version work together with standard 35 mm style boring patterns that account for this depth, so drilling operations can be set up once and applied across all matching doors in a run. Because the hinge belongs to the Blum Compact 30C family, installers working across multiple cabinets can maintain the same hinge style, appearance, and function throughout a project.
BLUMOTION integrated into the hinge cup gives each Blum Compact 30C hinge its own soft-close function, so every door using this hinge can close with a controlled deceleration built directly into the hinge body. The deactivation switch for small or light doors allows the BLUMOTION damping to be shut off on specific hinges, so narrow or low-mass doors can close firmly without the damper slowing them too early. The overload safety feature safeguards the BLUMOTION system inside the hinge under repeated or forceful use, so soft-close performance remains available across the life of the cabinet. Three dimensional cam adjustment supports precise door positioning in three planes, so an installer can correct for small drilling or mounting variances by dialing in reveals around each door after hanging. On production jobs or multi-cabinet installs, this adjustability lets the same hinge type be used across varying openings while still achieving uniform gaps and alignment. When combined with the defined 5/16 inch overlay and face frame application, these adjustment features support consistent results from cabinet to cabinet using the same hinge reference.
The Blum Compact 30C hinge is categorized as a concealed face frame hinge, so it is intended for cabinets built with a face frame front.
This hinge is specified as a 5/16 inch overlay hinge, so the cabinet door overlaps the face frame edge by 5/16 inch when positioned correctly.
The hinge has a 105 degree opening angle, so the cabinet door swings open to a wide angle suitable for everyday access to the cabinet interior.
BLUMOTION is integrated into the hinge cup, so the soft-close action is built directly into each hinge and controls the final closing movement of the door.
The hinge provides three dimensional cam adjustment, so door position can be tuned in multiple directions to set even gaps and reveals after mounting.
This hinge specifies a 7/16 inch cup depth, so the hinge cup bore in the door should be drilled to 7/16 inch to seat the hinge correctly.
The Blum Compact 30C hinge with BLUMOTION integrated soft-close, 5/16 inch overlay, and concealed face frame design offers a defined set of working details for cabinet builds using overlay doors on face frames. The 105 degree opening angle, three dimensional cam adjustment, and 7/16 inch cup depth translate into predictable boring, mounting, and alignment steps across each cabinet run. For projects that call for nickel-finished concealed cabinet hinges with integrated BLUMOTION in the hinge cup, this Blum 30C258B05 hinge provides a consistent reference point for specifying and repeating hardware across similar openings.
