Even before the door moves, the hardware stays out of sight. The compact module sits above the finished floor, with no cut-out in the floor, lintel, or ceiling. That makes the concealed pivot hinges easy to read in a technical sense and almost invisible once the door panel is closed. The surface-mounted pivot hinge format is the point here: two floor bolts, 45 mm deep, are enough to anchor the system without asking for embedded parts in advance.

Mounted on the finished floor, not built into it

The installation logic is straightforward. The pivot hinge without floor cut-out is fixed on top of the completed floor, so it can be used where there is already a finished surface underfoot. That detail matters in both new and existing homes, because the hinge does not depend on hidden construction zones below the floor finish. The result is a compact piece of metal hardware with a narrow footprint, set where the door can turn cleanly without visible floor hardware taking over the room.

In the door panel itself, the integrated pivot door hinge disappears into the construction. The source text makes that clear: on the floor, almost nothing remains visible. What you notice instead is the clean line of the door and the way the pivot point is absorbed into the panel. The concealed pivot hinges are not presented as a decorative object, but as a piece of hardware that lets the door stay visually calm while still carrying a substantial leaf.

Stealth Pivot NL and XL, each with a different reach

The system is documented in two variants. Stealth Pivot NL is designed for pivot doors up to 3000 x 1250 mm and up to 75 kg. Its pivot point can be placed either 9 cm or 13 cm from the wall. That gives a narrow, precise solution for doors that need to open 90° or 180°, with no embedded elements in the floor, lintel, or ceiling. It can be used free-standing or with a frame, depending on the door layout.

Stealth Pivot XL works at a larger scale. It is designed for pivot doors up to 3000 x 2200 mm and up to 150 kg. Here the pivot point can be placed at one-third of the door or in the middle, depending on the effect and swing required. The text also notes that the system can be used with or without a frame, and that the framed option supports acoustic and thermal sealing. For larger leaves, the concealed pivot hinges are doing more than just turning the door; they are carrying weight and keeping the movement controlled.

Opening angles and the hold position

The opening range differs by variant. NL allows 90° or 180° opening, while XL can be set to 180° or 360°. In both cases, the movement is described as silent, with a hold position at -90° and +90°. That hold position matters when a door needs to remain where it is placed instead of drifting back. The silent close and adjustable closing force make the movement feel measured rather than abrupt, which is especially relevant on a pivot door that turns from a central point rather than a side hinge.

The closing action is part of the technical character of the product. The adjustable closing force lets the hinge be tuned to the door’s weight and use, while the comfort close function is built into both variants. This is not shown as a soft visual effect, but as a working detail in the mechanism. For the NL version, the pivot hinge 75 kg limit sets a clear scale; for XL, the pivot hinge 150 kg capacity expands the same principle to larger doors.

A metal module defined by restraint

In the technical 3D view, the hinge reads as a black metal module with mounting points and visible adjustment features. The shape is compact and rectangular, with the kind of precise edge you expect from a component that has to stay hidden in daily use. The image does not try to dramatize the mechanism. Instead, it shows the hardware stripped down to its essentials: fixings, a long body, and the elements that make alignment possible. That visual restraint mirrors the product itself.

The concealed pivot hinges work by reducing what the eye has to process. There is no floor plate to visually interrupt the surface, no visible ceiling detail, and no structural hinge body left exposed around the opening. The door becomes the visible plane; the mechanism recedes into it. In a project page like this, that difference is the story. The product does not add a feature to look at. It removes one.

Why the details matter in use

The source material keeps coming back to installation and movement, which is where the product earns its place. A surface-mounted pivot hinge can be fixed on top of the completed floor, but still remain discreet once the door is in place. The integrated pivot door hinge system is therefore about more than appearance. It supports a clean turn, a controlled close, and a hold position that keeps the leaf where it is needed. Those are small operational details, yet they are the ones users feel every day.

Because the hinge does not require in-floor embedded parts, the installation can be adapted to different floor builds. That is a practical distinction, not a stylistic one. The system is described for new and existing homes, and that broad applicability comes from the minimal anchoring below the surface. In use, the door still reads as a pivot door; what changes is the amount of hardware the room has to show.

For a project page, that is the central point: the concealed pivot hinges are engineered to sit lightly in the room while working hard in the background. The black metal body, the precise mounting points, the adjustable closing force, and the hold positions all speak to a mechanism that is meant to be controlled rather than celebrated. What remains visible is the door itself and the clear movement it makes when the hinge is doing its work.

More information about the system can be found in the related partner profile and in other interior door projects that use pivot hardware with the same restrained visual logic.

The larger lesson is simple. A pivot door can carry weight, turn widely, and close quietly without asking for visible floor construction. That is what defines these concealed pivot hinges: a compact solution, mounted on the finished floor, integrated into the door panel, and built for doors that need to move cleanly without announcing the mechanism underneath.
