Rittal DK 7246.400 Rack Mounting Kit Grey Steel 3U 48.3 cm

The Rittal DK 7246.400 Rack Mounting Kit is a grey steel mounting solution intended for 3U equipment in standard 48.3 cm (19-inch) racks. Supplied as a pack of two, the kit provides durable steel mounting rails that support compact network, server or electronic modules while keeping rack space organized. The components are designed for reliable mechanical support and a consistent appearance in professional IT and industrial racks.

Advantages

Constructed from steel with a grey finish, the kit offers mechanical strength and resistance to deformation under typical rack loads. The 3U height allocation allows clear alignment with standard rack units while the 48.3 cm compatibility ensures fit in common 19-inch enclosures. Supplied as two matching pieces, the set simplifies installation of paired mounting points and reduces the need to source individual brackets.

Key specifications

How to use

Align the mounting pieces with the desired U positions in the 48.3 cm rack and fasten using appropriate rack screws or captive hardware. Ensure both pieces are level and securely tightened to provide stable support for installed equipment. For uneven loads, install additional support or distribute components across multiple U positions to maintain balance and prevent strain on mounting points.

Recommendations

Use standard 19-inch rack fastening hardware rated for the installed equipment weight. Inspect mounting points after installation and during maintenance cycles to verify tightness and absence of deformation. For heavy or vibration-prone equipment, consider supplemental support such as shelf brackets or front/rear rail pairs to increase stability.
