Blum 71B7650 CLIP top BLUMOTION 155° dual/half-overlay screw-on hinge – Onyx Black

The Blum 71B7650.ONS is a wide-opening concealed hinge for dual or half-overlay cabinet doors, where two doors share the same central partition. Its half-cranked arm supports the required door geometry while the 155° opening angle provides generous access to the cabinet interior.

The Onyx Black finish coordinates with dark cabinetry and contemporary furniture interiors. Integrated BLUMOTION controls the final closing movement, and the damping function can be deactivated on individual hinges when less resistance is required.

Dual and half-overlay planning

A dual or half-overlay application allows two cabinet doors to share the same central partition, with each door covering approximately half of the panel edge when closed. The half-cranked arm is designed for this arrangement and should not be treated as a full-overlay or inset hinge.

Clearance for drawers and pull-outs must be checked against the actual cabinet construction. The formal zero-protrusion designation applies to planned full-overlay configurations, so do not assume identical clearance in every half-overlay installation.

Door thickness and opening-angle control

The hinge is normally suitable for compatible doors between 20–24 mm thick. Doors up to 31 mm may be possible when the appropriate 92° opening-angle stop is used. For cabinet side panels between 23 mm and 34 mm thick, a 110° opening-angle stop may be required to prevent binding.

Use the complete planning dimensions and carry out a trial installation for thick, mitred or specialist fronts before fitting the complete cabinet.

Screw-on cup fixing

The 35 mm hinge cup is secured to the cabinet door with screws. Screw-on describes the hinge-cup fixing, not the cabinet mounting plate. The CLIP connection to a compatible mounting plate is tool-free.

A compatible Blum CLIP mounting plate must be selected and ordered separately for the required door position and cabinet construction.

Frequently Asked Questions

What does dual or half overlay mean?

It means two cabinet doors share the same central partition, with each door covering 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 required.

What does screw-on fixing mean?

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

Is the mounting plate included?

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

Can it be used with doors thicker than 24 mm?

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

Can the 155° opening be restricted?

Yes. Compatible stops can reduce the opening angle 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.
