Arlu® (Argenta) Invisible Neo Concealed Hinge L7

Heavy-duty capacity. Zero visible screws. Effortless single-person mounting for grand doors.

Grand Architecture Deserves Seamless Perfection

When interior design scales up, hardware shouldn’t get in the way.

Picture a massive, floor-to-ceiling door panel swinging open with effortless grace. No bulky industrial hinges disrupting the sightline. No exposed alignment screws cluttering the timber. Just clean, unbroken architectural lines where the door meets the frame.

That is the power of the Arlu® Invisible Neo L-7.

Engineered in Belgium and honored with the prestigious Red Dot Design Award, the Invisible Neo L-7 is the heavyweight champion of concealed hinges. Built for oversized, extra-heavy doors up to 150kg, it allows massive panels to rest completely flush against the wall while opening to a full 180°. Best of all, matching cover plates keep every single screw hidden away, open or closed.

Massive Doors. Effortless Solo Setup.

Hanging oversized interior doors usually requires a whole installation crew and a afternoon of wrestling with alignment.

Here’s where it gets clever…

Despite its extreme load rating, the L-7 features Arlu’s patented Easy-Hook® system. The hinge separates easily into door and frame components, allowing a single installer to hook and mount even massive door panels safely into place—no extra hands needed.

Once mounted, fine-tuning is simple. Using a standard Allen key, you can adjust alignment across three dimensions (height, width, and depth/pressure) without removing the door from its frame.
