PRODUCT DESCRIPTION
Blum 71B3790 CLIP top BLUMOTION 110° inset INSERTA hinge – Onyx Black
The Blum 71B3790 is a concealed CLIP top hinge for inset cabinet doors that close inside the cabinet opening. Its cranked arm positions the door within the cabinet rather than allowing it to cover the front edge of the cabinet side.
The Onyx Black finish suits dark cabinetry and contemporary furniture interiors. Integrated BLUMOTION soft close controls the final movement of the door, and the damping function can be deactivated on individual hinges when less closing resistance is required.

Inset cabinet-door planning
An inset door closes inside the cabinet opening and normally sits flush with the front edges of the cabinet sides. Door thickness, cup drilling distance, mounting-plate position and the required clearance around the door all affect the installation, so check the complete door and cabinet dimensions before drilling.
The cranked arm is designed for the geometry required by an inset application. Do not substitute a straight-arm overlay hinge when the door must sit inside the opening.
Tool-free INSERTA installation
Prepare a 35 mm hinge-cup hole approximately 13 mm deep, together with two 8 mm fixing holes on 45 mm centres. Position the cup in the prepared drilling and operate the integrated INSERTA locking mechanism. The built-in expanding dowels secure the hinge cup without separate fixing screws.
Mounting plate required
A compatible Blum CLIP mounting plate must be ordered separately. For inset applications, select the mounting-plate position and height to suit the door thickness, cabinet construction and required clearances. Test the door movement before final adjustment.
