The item is a set of four swivel castors for server and network enclosures from Vertiv (formerly Knürr), specifically designed for mounting on Miracel enclosures. The castors enable mobile positioning of the enclosure frame and allow for easy movement in data centers, server rooms, or during maintenance work. The castors are equipped with an M12 threaded bolt, which is screwed into the designated threaded holes of the Miracel base frame. Each individual castor has a diameter of 75 mm and is rated for a load capacity of 100 kg, ensuring stable and secure movement of the loaded enclosure.

Swivel castors enable flexible and quiet movement in all directions, allowing the enclosure to be easily positioned even in confined spaces or complex layouts. The construction is designed for use in professional IT and electrical installations, with materials and mounting method focused on high load capacity and durability. Mounting is done directly onto the integrated threaded holes of the Miracel base frame, eliminating the need for additional fastening elements.

Load capacity of 100 kg per castor means the entire set can safely carry a total load of up to 400 kg, which is sufficient for most standard enclosure configurations. The M12 threaded bolts ensure a secure and rotation-resistant connection to the enclosure frame, with the threaded connection being standardized and compatible with the designated mounting points of Miracel enclosures. The castors with 75 mm diameter provide sufficient wheel profile for smooth movement on flat surfaces, including slightly uneven flooring in server rooms.

The castors are designed as accessories for Miracel enclosures and serve to enhance the mobility of the enclosure frame. They are not intended for other enclosure models or manufacturers, but specifically for mounting on the threaded holes of the Miracel base frame. Mounting requires no additional tools or fastening elements, as the threaded bolts are directly screwed into the designated threaded holes.

Compatibility is limited to the Miracel enclosure series, particularly base frames that feature the corresponding threaded holes for M12 bolts. The castors are intended as replacement or supplementary parts for existing enclosure configurations to increase mobility without compromising the stability or safety of the enclosure.

The function of the castors is to make the enclosure easily movable during maintenance, installations, or relocations. The swivel castors allow precise control of movement direction, enabling the device to be maneuvered even in narrow aisles or tight spaces. The load capacity of 100 kg per castor ensures that even heavily loaded enclosures can be moved safely, without overloading the castors or mounting points.

Mounting is done by simply screwing the M12 threaded bolts into the designated threaded holes of the Miracel base frame. The castors are pre-mounted onto the bolts, so no additional assembly steps are required. The fastening is mechanically stable and does not require additional holding or securing elements.

Operational advantages include increased flexibility and mobility of the enclosure. The castors enable quick and secure positioning, especially during maintenance or when installing new components. The load capacity of 100 kg per castor ensures safe movement even under heavy loads, minimizing the risk of damage or accidents. The swivel castors offer precise control, allowing the device to be maneuvered even in confined spaces.
