Blum 71B7650 CLIP top BLUMOTION 155° Half-Overlay Screw-On Hinge – Onyx Black

The Blum 71B7650.ONS is a wide-opening CLIP top BLUMOTION hinge for half-overlay or dual cabinet-door applications, finished in distinctive Onyx black.

Its half-cranked hinge arm is designed for installations where two cabinet doors share the same central partition. The generous 155° opening angle provides improved access to cabinets containing internal drawers, pull-out shelves, storage baskets and other interior fittings.

Integrated BLUMOTION soft closing

BLUMOTION damping is integrated discreetly into the hinge, controlling the door during the final stage of closing for smooth and quiet movement.

The BLUMOTION mechanism can be switched off on individual hinges when required, which can be useful with smaller or lighter cabinet doors.

Screw-on hinge-cup fixing

This model uses a conventional screw-on 35mm hinge cup for attaching the hinge to the cabinet door. The screw-on fixing refers to the hinge cup — it does not mean that a cabinet mounting plate is included.

Once fitted, the CLIP mechanism allows the door to be attached to or removed from a compatible mounting plate without tools.

Wide-opening cabinet access

The 155° movement provides excellent access to the cabinet interior. However, Blum’s formal zero-protrusion designation applies specifically to planned full-overlay configurations within this hinge family.

Clearance for internal drawers and pull-outs should therefore be checked for the actual half-overlay cabinet construction rather than assumed automatically.

Door-thickness planning

The hinge is normally suitable for compatible doors between 20mm and 24mm thick.

Doors up to 31mm may be possible when the 92° opening-angle stop is used. For cabinet side panels between 23mm and 34mm thick, Blum specifies a 110° opening-angle stop to prevent binding. A trial installation is recommended for thick or specialist fronts.

Technical specifications

Frequently Asked Questions

What does half overlay or dual application mean?

It means two cabinet doors can share the same central partition. Each door covers approximately half of the panel edge when closed.

Does this hinge include soft-close?

Yes. BLUMOTION soft-close is integrated into the hinge and can be deactivated when necessary.

What does zero protrusion mean?

A correctly planned zero-protrusion application moves the open door clear of the cabinet interior so pull-outs can extend. This must be checked for the actual half-overlay cabinet construction.

What does screw-on fixing mean?

The 35mm hinge cup is secured to the cabinet door using screws. It does not mean that the separate cabinet mounting plate is supplied.

Is the mounting plate included?

No. A compatible Blum CLIP mounting plate must be selected separately according to the required overlay and cabinet construction.

Can it be used with doors thicker than 24mm?

Doors up to 31mm may be possible with the appropriate 92° opening-angle stop. A trial installation is recommended.

Can the 155° opening be restricted?

Yes. Compatible stops can reduce the opening to approximately 110° or 92° where additional clearance control is required.

Is this the same as the nickel 71B7650 hinge?

The function and geometry are equivalent, but this version has the Onyx black finish and the full designation 71B7650.ONS.

Is the hinge supplied individually?

Yes. This listing contains one hinge. The cabinet mounting plate is not included.
