PRODUCT DESCRIPTION
Blum 70T3790.TL CLIP top 110° Inset Unsprung INSERTA Hinge
The Blum 70T3790.TL is an unsprung concealed cabinet hinge for inset doors that close within the cabinet opening. Its fully cranked hinge arm provides the geometry required for a correctly planned inset-door installation.
This hinge has no internal closing spring, allowing the door to move freely without being pulled closed. It is particularly suitable for handleless furniture using a compatible, correctly positioned Blum TIP-ON push-to-open device.
The INSERTA hinge cup provides tool-free attachment to a correctly drilled door. The 35mm cup and expanding fixings lock into the prepared drilling pattern without conventional hinge-cup screws.
Blum’s CLIP connection also allows the hinge arm to attach to or release from a compatible cabinet mounting plate without tools.
Supplied as one hinge. The mounting plate, TIP-ON device and cabinet fixings are sold separately.

Inset-door planning
An inset door closes inside the cabinet opening rather than covering the cabinet side panels. The required clearance depends on the door thickness, hinge-cup drilling distance, mounting-plate height and the gap required around the door.
Do not assume every inset installation uses the same mounting plate. Calculate the application using the actual cabinet and door dimensions, and complete a trial installation before drilling multiple doors.
INSERTA installation
The door requires a 35mm hinge-cup bore plus two accurately positioned 8mm fixing holes. Insert the hinge into this prepared pattern and close the INSERTA locking mechanism to secure the expanding fittings inside the door.

Frequently asked questions
What is an inset hinge?
An inset hinge is used where the closed cabinet door sits within the cabinet opening rather than overlaying the cabinet side panels.
What does unsprung mean?
An unsprung hinge has no internal closing spring. The door moves freely and will not pull itself into the closed position.
Is it suitable for TIP-ON push-to-open doors?
Yes. Its free-swing action makes it suitable for a correctly selected and positioned Blum TIP-ON device.
Can a BLUMOTION damper be added?
BLUMOTION is not recommended for the intended free-swing TIP-ON application because damping can resist the movement required for push-to-open operation.
What does INSERTA mean?
INSERTA is Blum’s tool-free hinge-cup fixing system. It secures the cup to an accurately drilled door without conventional hinge-cup screws.
Is an INSERTA back plate purchased separately?
No. The INSERTA fixing mechanism is part of the hinge. The separate cabinet mounting plate must be purchased separately.
Is the mounting plate included?
No. Select the appropriate Blum CLIP mounting plate according to the cabinet construction and required inset-door position.
Can the door be removed without tools?
Yes. The CLIP connection allows the hinge arm to be released from its mounting plate without removing the hinge cup from the door.

This listing is for one hinge.
