PRODUCT DESCRIPTION
Blum 71T6680 CLIP top 170° Half-Overlay Knock-In Hinge
Use this wide-angle hinge on a shared central cabinet partition where two doors need a dual or half-overlay layout. The Blum 71T6680 has a cranked arm, a 170° opening and a spring that draws the door closed. Its nickel-plated knock-in cup with dowels is pressed into a correctly prepared door. The word “dual” describes the application; one hinge is supplied under Hart Wholesale SKU HI71T6680.
Fit the knock-in cup correctly
The existing 71T6680 listing identifies a 35 mm cup with an 11 mm depth and two dowel fixings. Use suitable insertion equipment and the complete part-specific Blum drilling diagram before machining; do not substitute a screw-on or INSERTA fixing procedure. Knock-in refers to the door-side cup, while the arm clips onto a separately selected compatible Blum CLIP mounting plate on the cabinet. The mounting plate is not supplied with this hinge.
Plan the half-overlay door path
The two doors cover parts of the shared panel rather than the larger front overlay of a straight-arm hinge. Cup position, mounting-plate height, front thickness and cabinet geometry determine the finished gap. Wide opening does not automatically mean zero protrusion or unobstructed access for inner drawers. Check clearance against nearby handles, panels and pull-outs using the correct planning data; do not assume a universal 24 mm door-thickness limit or a child-safety recommendation for this exact setup.
Sprung closing, optional damping
The closing spring pulls the door towards closed, but integrated BLUMOTION is not included. A separately matched clip-on damper may be suitable; check the exact accessory and hinge compatibility before ordering. Compare the 71T6640B half-overlay INSERTA or 71T6650 half-overlay screw-on if those door-fixing methods are required instead.

Frequently Asked Questions
What does half-overlay mean?
Two doors hinge on opposite sides of one central partition and each covers part of that shared panel.
Does dual mean two hinges are supplied?
No. One hinge is supplied.
What does knock-in mean?
The cup dowels are pressed into correctly prepared door drillings with suitable insertion equipment.
Is knock-in the same as INSERTA?
No. These are different door-side fixing systems. Match the hinge version to the exact drilling plan.
Does the hinge have built-in soft close?
No. It has sprung closing without integrated BLUMOTION; a separately verified damper may be an option.
Is the mounting plate included?
No. Choose and purchase a compatible CLIP cabinet plate separately.
Does 170° guarantee clearance for internal drawers?
No. Check the actual door path, protrusion and cabinet geometry first.
