PRODUCT DESCRIPTION
Blum 75T1780 CLIP Top 107° Inset Knock-In Hinge
The Blum 75T1780 is a professional-quality, sprung concealed hinge designed for inset cabinet doors. Its fully cranked hinge arm positions the door inside the cabinet opening, while the 107° opening angle provides comfortable access for kitchen, bedroom and fitted furniture applications.
The shallow 11.5mm minimum cup drilling depth makes this hinge suitable for cabinet fronts approximately 15–24mm thick, subject to the door material, drilling position and a trial installation.
Important: this is a standard sprung, self-closing CLIP top hinge. It does not contain integrated BLUMOTION soft-close.
Designed for inset cabinet doors
An inset door sits within the cabinet opening rather than covering the cabinet sides. The final reveal around the door depends on the mounting plate height, cup drilling distance, front thickness and edge radius. A trial installation is recommended before drilling every door.
Knock-in cup fixing
The hinge cup has pre-mounted dowels that are pressed into prepared 8mm fixing holes. This provides a secure, repeatable fixing for production and workshop assembly. The knock-in cup is mechanically fitted and should not be described as tool-free.
Once installed in the door, the hinge arm connects to a compatible mounting plate using Blum’s tool-free CLIP mechanism. This allows the door to be attached and removed without disturbing the mounting plate adjustment.

Frequently asked questions
Does the Blum 75T1780 have soft-close?
No. The 75T1780 has a spring that pulls the door closed, but it does not contain integrated BLUMOTION damping.
What does inset application mean?
An inset door fits within the cabinet opening rather than overlapping the cabinet sides. The fully cranked hinge arm provides the geometry required for this application.
Is the knock-in cup tool-free?
No. The pre-mounted dowels are pressed into prepared 8mm holes. The CLIP connection between the hinge arm and mounting plate is tool-free.
What drilling pattern is required?
The hinge requires a 35mm cup hole with a minimum depth of 11.5mm. The two 8mm fixing holes are positioned on 45mm centres.
What door thickness can be used?
The hinge is intended for fronts approximately 15–24mm thick. Door material, edge profile and drilling position should be checked with a trial installation.
Is a mounting plate supplied?
No. Order a compatible Blum CLIP top mounting plate separately. The mounting plate height must be selected to suit the required inset reveal.
Is the hinge sold as a pair?
No. Each quantity ordered supplies one hinge.
