The Rittal VX IT 5302109 is a 48,3 cm ( 19 inch ) profile rail in standard design, specifically developed for use in the VX IT enclosure system. It serves to create a metric mounting plane in the rear area of the enclosure and is designed for an enclosure height of 47 U (2,200 mm). The profile rail is made of steel sheet with a thickness of 2 mm, is primed, and finished in the colour RAL 9005. The L-shaped design enables direct mounting of server and IT mounting kits, which are secured to the 48,3 cm ( 19 inch ) system hole pattern.

Applications
The profile rail is intended for use in IT and server enclosures of the VX IT system, where structured and standardised mounting of devices is required. It is installed in the rear area of the enclosure to create a stable mounting plane for 48,3 cm ( 19 inch ) devices. The metric mounting plane enables integration of standard IT components based on the EIA 310 E standard.

Functions and Equipment in Detail
The rail features side round and square holes in the U grid, enabling precise and flexible mounting of cable management elements and other components. The integrated, bidirectional U labelling facilitates orientation and identification of mounting positions. The metric mounting hole pattern including U centre mounting according to standard EIA 310 E ensures compatibility with common IT and server components. Equipotential bonding within the mounting plane and to the frame is achieved via the mounting elements, ensuring electrical safety and grounding.

Technology Explained Simply
The profile rail is made of steel sheet (2 mm), providing sufficient stability for mounting IT devices. The surface is primed, representing a prepared layer for subsequent painting or coating. The colour RAL 9005 is a dark grey standard tone commonly used in IT infrastructures. The L-shaped form ensures the rail can be mounted on both the front and side walls of the enclosure, creating a stable mounting plane.

Compatibility and Accessories
The profile rail is designed for use with other components of the VX IT system. For mounting, a combination with cross brace, depth brace, or mounting angle is required. These elements allow flexible adaptation to various enclosure dimensions. Mounting options include alternative mounting widths from 53,3 cm ( 21 inch ) to 61 cm ( 24 inch ), depending on the chosen mounting method and enclosure dimensions. Compatible accessories include, for example, the VX IT depth brace for 48,3 cm ( 19 inch ) standard 700/800x1200 mm, the VX IT cross brace for 48,3 cm ( 19 inch ) stand/dyn 800 mm, and the VX IT mounting angle for 48,3 cm ( 19 inch ) standard, W: 600 mm.

Mounting and Installation
Mounting takes place in the rear area of the enclosure. Installation requires the use of additional elements such as cross brace, depth brace, or mounting angle, selected according to the enclosure dimensions. The exact mounting instructions are described in the manufacturer’s data sheet, with the selection of mounting elements depending on the specific enclosure configuration.

Operational Advantages
The profile rail provides a stable and standardised mounting plane for IT components, which are directly mounted to the 48,3 cm ( 19 inch ) system hole pattern. The integrated U labelling and the system hole pattern in the U grid simplify structuring and documentation of the installation. The use of mounting elements ensures secure equipotential bonding, which is important for electrical safety in IT infrastructures. The product is delivered incl. mounting material, simplifying installation. The packaging unit contains 2 pcs.
