PRODUCT DESCRIPTION
Blum 73B3550 CLIP top BLUMOTION 110° Large-Overlay Screw-On Hinge – Onyx Black
The Blum 73B3550 CLIP top BLUMOTION special hinge provides increased overlay capacity for full-overlay cabinet doors fitted to thicker cabinet sides. Its specialised hinge-arm geometry allows the door to cover more of the cabinet side than a standard Blum 71B3550 overlay hinge.
Depending on the selected mounting plate, hinge-cup drilling distance and adjustment, the 73B3550 can provide overlay values up to approximately 20mm. The correct application must be calculated before drilling the cabinet door.
The Onyx Black finish complements dark kitchen units, bedroom furniture, display cabinets and contemporary cabinetry where the hinge may be visible when the door is open.
Special large-overlay geometry
A standard overlay hinge may not provide sufficient door coverage when used with a thick cabinet side. The 73B3550 has increased overlay capacity, helping position the closed door correctly across the front edge of the cabinet.
The 20mm measurement relates to the potential door overlay in a correctly planned application. It should not be treated as a universal maximum door-thickness specification.
Integrated BLUMOTION soft close
Blum's BLUMOTION technology is integrated inside the hinge, providing a smooth, quiet and controlled closing action without requiring a separate soft-close adapter.
The BLUMOTION function can be deactivated on individual hinges when necessary. This can help achieve the correct closing movement on smaller or lightweight cabinet doors.
Screw-on hinge-cup fixing
This model uses a traditional screw-on hinge cup. The 35mm cup is fitted into a correctly prepared boring and secured to the back of the cabinet door using suitable fixing screws.
Screw-on describes how the hinge cup is attached to the door. It does not refer to the separate cabinet-side mounting plate.

Frequently asked questions
What is a special large-overlay hinge?
It is a hinge with increased overlay capacity, designed for applications where a standard overlay hinge does not cover enough of a thick cabinet side.
What is the difference between 73B3550 and 71B3550?
The 73B3550 provides greater overlay capacity for thicker cabinet sides. The 71B3550 is the conventional full-overlay hinge for standard cabinet construction.
Does the 20mm measurement refer to door thickness?
No. It relates to the potential overlay that can be achieved in a correctly planned application. The final result depends on the mounting plate and drilling distance.
Does this hinge include soft close?
Yes. BLUMOTION soft close is integrated into the hinge and can be deactivated on individual hinges when required.
What does screw-on mean?
It means that the 35mm hinge cup is secured to the cabinet door with screws. It does not describe the fixing method used by the separate mounting plate.
Is the mounting plate included?
No. A compatible Blum CLIP cabinet-side mounting plate must be selected and ordered separately.
Can the opening angle be restricted?
Yes. A compatible Blum 70T3553 opening-angle stop can reduce the opening from 110° to approximately 86°.
Should I carry out a trial installation?
Yes. A trial installation is recommended whenever the required overlay is close to the maximum available or the cabinet construction differs from a standard application.
