Product Information
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.

FAQs
General Questions
A concealed hinge, also known as a hidden or invisible hinge, is a type of hinge designed to be completely hidden when the door is closed. Unlike traditional hinges, concealed hinges enhance the aesthetic appeal by providing a clean and seamless look.
Concealed hinges are widely used in residential, commercial, and public spaces. They are particularly popular in minimalist designs, luxury interiors, and high-traffic areas where aesthetics and functionality are paramount.
Benefits of Concealed Hinges
- Sleek Design: They provide a flush, screw-free appearance, enhancing the overall aesthetic of the door and space.
- Durability: Built to withstand frequent use, they are often cycle-tested for long-term reliability.
- Safety Features: Many concealed hinges offer finger protection by minimizing gaps between the door and the frame.
- Adjustability: Most concealed hinges provide 3D adjustment (height, width, and depth) for precise alignment.
- Wide Opening Angle: They typically allow for larger opening angles, up to 180°, improving accessibility.
Concealed hinges are designed to support significant door weights while maintaining smooth and durable operation. When installed correctly, they can perform as well as or better than traditional hinges, especially for modern applications.
Compatibility and Applications
Yes, concealed hinges are suitable for a wide range of doors, including:
- Lightweight doors: with smaller hinges
- Medium-weight doors
- Heavy doors: with larger, load-bearing hinges</ br>It’s essential to select the correct hinge size and model for the specific door type and weight.
Most concealed hinges are universally compatible, meaning they can be used for both left- and right-opening doors.
Yes, concealed hinges can often be installed on existing doors, provided there is enough material in the door and frame to accommodate the hinge. However, some retrofitting may be required.
Installation and Adjustments
Many concealed hinges are designed for easy installation. Features like pre-aligned templates and innovative mechanisms (e.g., ‘easy hook’ designs) simplify the process. However, precise measurements and careful installation are essential to achieve optimal results.
Common tools include a drill, screws, screwdrivers, and sometimes a router for creating hinge recesses. Some concealed hinges come with installation guides or templates for added convenience.
3D adjustability refers to the ability to adjust the hinge in three dimensions:
- Height: Up or down for proper door positioning.
- Width: Side-to-side for perfect alignment.
- Depth: In or out for flush fitting with the frame.</ br>This feature ensures precise alignment and smooth door operation, even after installation.
Maintenance and Durability
Concealed hinges are highly durable and often tested for long-term use, typically exceeding 200,000 open-close cycles. They are made from robust materials to withstand wear and tear.
Minimal maintenance is required. Occasional cleaning and lubrication may be needed to ensure smooth operation. It’s also a good idea to periodically check alignment and make adjustments if necessary.
Design and Aesthetic
No, concealed hinges are designed to hide screws, even when the door is open. This provides a clean and seamless appearance.
Yes, concealed hinges are perfect for minimalist and modern designs. They keep the focus on the door and room’s architecture by eliminating the visual clutter of traditional hinges.
Troubleshooting
Check the alignment using the hinge’s 3D adjustability features. Adjust the height, width, or depth to ensure proper positioning. If the problem persists, verify the installation measurements.
Replacing concealed hinges is relatively straightforward if you use the same hinge model. For different models, you may need to adjust or expand the hinge recess.
Additional Information
Yes, certain models of concealed hinges are designed specifically for heavy or large doors. Be sure to choose a hinge with the appropriate weight and size rating.
Many concealed hinges are compatible with fire-rated doors, but it’s essential to confirm the hinge’s certification and specifications for fire-rated applications.
While the hinge is mostly concealed, some models offer different finishes for visible components to match the door or frame’s design.
For assistance, contact the retailer or manufacturer where you purchased the hinge. They can provide technical support, replacement parts, or additional resources.
