PRODUCT DESCRIPTION
Blum CLIP top BLUMOTION 110° Knock-In Hinge (71B3580)
The Blum 71B3580 is engineered specifically for high-efficiency kitchen manufacturing and commercial workshop assembly. Featuring integrated expanding split dowels, this full overlay hinge eliminates the need for manual wood screws, allowing trade professionals to secure the hinge cup rapidly using a specialised press or knock-in tool.
Once fitted to a compatible Blum CLIP mounting plate, the cabinet door can be attached and removed without tools. Three-dimensional adjustment allows accurate door alignment after installation.
Important: Installation Requirement
This is a specialised trade variant. It requires cabinet doors to be pre-drilled with two 8mm pilot holes alongside the standard 35mm hinge cup hole on 45mm fixing centres. If you are replacing hardware on standard hand-drilled kitchen doors without 8mm dowel holes, please order the Blum 71B3550 screw-on hinge instead.

Complete your setup
Maximise workshop efficiency by pairing this rapid-assembly hinge with genuine Blum cruciform mounting plates. The correct mounting-plate height depends on the required door overlay and cabinet construction.
Integrated BLUMOTION soft closing
BLUMOTION is built directly into the hinge and provides smooth, controlled closing even when the cabinet door is closed with force. No separate soft-close adapter is required.
The BLUMOTION mechanism can be deactivated on an individual hinge. This is useful where a small or lightweight door requires less damping.
Knock-in cup installation
The 71B3580 requires a 35mm hinge-cup drilling and two 8mm fixing holes positioned on 45mm centres. The steel dowels are pressed into the prepared holes to secure the hinge cup to the door.
Note: the knock-in boss is normally installed using suitable hinge-insertion equipment or a press-in ram. It is different from Blum INSERTA, which uses a locking flap for tool-free cup installation without insertion machinery.

Frequently Asked Questions
Does the Blum 71B3580 include soft close?
Yes. The BLUMOTION soft-close mechanism is integrated directly into the hinge.
Can BLUMOTION be switched off?
Yes. The damping mechanism can be deactivated on an individual hinge when less closing resistance is required.
What is the difference between knock-in and INSERTA?
A knock-in hinge uses steel dowels that are pressed into the prepared fixing holes, normally with insertion equipment. INSERTA uses a locking mechanism that secures the hinge cup without insertion machinery.
What drilling pattern is required?
The hinge requires a 35mm cup hole and two 8mm fixing holes positioned on 45mm centres. The hinge-cup drilling depth is 13mm.
Is a mounting plate included?
No. A compatible Blum CLIP mounting plate must be selected and purchased separately.
What does overlay application mean?
Overlay means the closed cabinet door sits in front of and covers the cabinet side panel. The final overlay depends on the drilling distance, mounting-plate height and hinge adjustment.
Can the opening angle be restricted?
Yes. The Blum 70T3553 opening-angle stop reduces the opening angle from 110° to approximately 86°.
