Heavy-duty performance. Zero visible screws. Effortless single-person mounting.
Heavy Doors Deserve an Invisible Touch
Who says heavy-duty doors have to look industrial?
Step into a space where substantial interior doors glide effortlessly, leaving behind a completely seamless, flush finish. No unsightly hinge knuckles protruding from the frame. No exposed hardware cluttering your design.
Enter the Arlu® Invisible Neo M-6.
Engineered in Belgium and honored with the prestigious Red Dot Design Award, the Invisible Neo M-6 brings uncompromising strength to modern architecture. Built for thicker, heavier doors, it allows panels to sit entirely flush while swiveling up to a full 180°. Even when wide open, matching cover plates keep every single screw completely out of sight.
Built for Strength. Installed with Ease.
Hanging heavier interior doors usually means calling in extra hands and wrestling with alignment.
Here’s where it gets clever…
Despite its heavy-duty capacity, the M-6 features Arlu’s patented Easy-Hook® system. A single installer can easily hook and mount the door panel directly into the frame—saving time, labor, and frustration.
Once hung, fine-tuning is effortless. You can adjust alignment across three dimensions (height, width, and depth/pressure) using a standard Allen key without removing the door.

Number of concealed hinges depending on the door weight and a maximum
door size of 2000 mm (height) x 1000 mm (width) in accordance with EN1935:
| 2 hinges | Max. 80 kg |
| 3 hinges | Max. 100 kg |
*To ensure the door leaf remains perpendicular, the use of at least 3 hinges is recommended. Using more than 4 hinges is not recommended; please contact ARLU if this is necessary.
Adjusted door weight:
According to the EN1935 standard, door closers increase the load on the door hinges and their wear and tear.
This must be taken into account for the correct calculation.
| door closer | door weight +20% |
| door closer with back-check | door weight +75% |
| for intensive use | door weight +75% |
When using a door closer, we recommend using 4 hinges:
2 at the top, 1 in the middle and 1 at the bottom.
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.
- 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.
- Lightweight doors: with smaller hinges
- Medium-weight doors
- Heavy doors: with larger, load-bearing hinges
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.
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.
- 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.
This feature ensures precise alignment and smooth door operation, even after installation.
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.
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.
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.
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.
