PRODUCT DESCRIPTION
Blum 71T3690 CLIP top 110° Half-Overlay INSERTA Hinge
The Blum 71T3690 is a sprung concealed hinge for dual or half-overlay cabinet doors. A cranked arm positions two doors hinged on opposite sides of a shared central partition, each covering part of that panel. “Dual” names the application, not a two-piece pack: one purchase supplies one hinge.
Tool-free INSERTA cup, separate cabinet plate
The 35 mm hinge cup locks into an accurately drilled door with Blum’s INSERTA mechanism, without conventional cup-fixing screws. This model’s existing technical data specifies two 8 mm fixing holes on 45 mm centres, a 13 mm cup drilling depth and 3–7 mm drilling distance. Confirm the full drilling pattern and front clearance against current Blum planning information before machining. INSERTA applies to the door-side cup; a compatible Blum CLIP mounting plate still needs to be purchased and fixed separately to the cabinet. The hinge arm clips onto that plate without tools for door removal and rehanging.
Sprung closing and fitting choices
The 110° hinge spring draws the door closed. There is no integrated BLUMOTION soft close. Existing product data lists ±2 mm side and +3/−2 mm spiral-screw depth adjustment, with height adjustment through the chosen plate. Plate spacing, cup position, door thickness and cabinet geometry determine the final half-overlay gap; do not assume the previously listed 24 mm door-thickness figure applies to every front. For conventional cup screws instead of INSERTA, see the 71T3650 half-overlay screw-on hinge. For a straight-arm full-overlay INSERTA version, see the 71T3590 overlay hinge. Check drilling and plate requirements before substitution.

Frequently Asked Questions
Does 71T3690 have soft close?
No. It is sprung and self-closing, but has no integrated BLUMOTION.
What does INSERTA mean?
It is a tool-free locking method for fitting the hinge cup into a correctly prepared door without cup-fixing screws.
Does INSERTA refer to the mounting plate?
No. It describes cup-to-door fixing. A separately selected cabinet mounting plate still requires appropriate fixing.
Is this for half-overlay doors?
Yes. Its cranked arm is intended for a dual/half-overlay arrangement around a shared partition.
Is the mounting plate included?
No. One hinge is supplied; the compatible plate is purchased separately.
Can the fitted door be removed without tools?
Yes. Release the arm from its CLIP mounting plate without removing the INSERTA cup from the door.
