One-unit rack shelf with a 483 mm width and 250 mm depth. Powder-coated steel construction with a ventilated surface for stable support and airflow.
No-sag support - with 1.5mm powder-coated steel construction
Steel panels of 1.5 mm thickness combine stiffness with a protective powder-coated finish, reducing flex under load. Robust mounting points transfer weight evenly across the 19-inch frame.
Reliable support for heavier rack-mounted equipment keeps shelves level over time. Suitable where sustained stability matters, such as network switches and compact servers.
Improved cooling - with a ventilated shelf surface
Strategic openings in the shelf allow convective airflow around installed devices, letting heat escape rather than collecting beneath equipment. Ventilation helps passive cooling without added fans.
Reduced hotspot risk for heat-generating components when mounted inside enclosed cabinets. Helpful for installations that rely on natural airflow to manage temperatures.
Straightforward fit - with universal 19-inch width and compact 250 mm depth
Standard 19-inch (483 mm) mounting aligns with typical rack rails while the 250 mm depth accommodates shallow and standard equipment. Universal fixing points suit common cabinet layouts.
Quick installation into existing 19-inch racks without custom adaptors. Compact depth makes the shelf a good match for shallow cabinets or densely populated racks.
