The Triton RAB-UP-450-A4 is a 48,3 cm ( 19 inch ) shelf base in 1HE format, made of perforated steel sheet in black (RAL9005). It serves as a stable base for devices in server or network rooms that cannot be directly mounted to the 48,3 cm ( 19 inch ) profile rails, such as converters, routers, NAS systems or external USB hard drives. The shelf base is designed for a maximum load of 80 kg, with load capacity varying depending on installation depth: 15 kg at 150 mm depth, 20 kg at 250 mm, and 50 kg at 350 mm. The installation depth of the base ranges from 382 mm to 550 mm, making it suitable for cabinets with a minimum depth of 600 mm. Mounting is done to the front and/or rear 48,3 cm ( 19 inch ) profile rail, with mounting brackets pre-punched on the underside of the shelf base and broken out during installation.

Shelf base
The shelf base is made of steel sheet and provides a robust, flat surface. The perforated surface allows for good air circulation, which is particularly beneficial when mounting heat-generating devices such as network routers or storage units. The black color (RAL9005) ensures a uniform visual appearance in the server room. The dimensions of the shelf base conform to the standard for 48,3 cm ( 19 inch ) rack systems, with a depth of 450 mm. The maximum load capacity of 80 kg is achieved at an installation depth of 350 mm, with load capacity reduced accordingly at lesser depths.

Applications
The shelf base is designed for use in 48,3 cm ( 19 inch ) server and network cabinets, particularly in environments where devices without direct rack-mount capability need to be installed. It is suitable for mounting devices that require a stable, flat surface without the possibility of direct rail mounting. The installation width of 450 mm and compatibility with cabinets from 600 mm depth make it a universal solution for many standard rack systems.

Functions and equipment in detail
The shelf base is supplied with a complete mounting material set, including the necessary screws, washers and cage nuts. This includes 8x screws M6x10 mm, 8x plastic washers, 8x cage nuts M6, 8x screws M5x12 mm, and 4x rear brackets. The mounting brackets are pre-punched into the shelf base and can be broken out during installation, simplifying the process. Mounting is done to the front and/or rear 48,3 cm ( 19 inch ) profile rail, with the exact number of mounting elements varying according to installation depth: 4x screws, washers and cage nuts are required for 150 mm and 250 mm depths, while all 8 elements are needed for 350 mm depth.

Technology explained simply
The construction of the shelf base from perforated steel sheet ensures sufficient stability while allowing ventilation. The perforated surface enables free air exchange, supporting cooling of devices mounted below. Mounting to the front and/or rear profile rail ensures secure anchoring in the rack, with the pre-punched mounting brackets simplifying installation. The maximum load capacity of 80 kg is achieved at an installation depth of 350 mm, with load capacity reduced accordingly at lesser depths. The black color (RAL9005) blends visually into most server environments.

Compatibility and accessories
The shelf base is designed for 48,3 cm ( 19 inch ) rack systems and can be installed in cabinets with a minimum depth of 600 mm. The installation depth of the base is 382 to 550 mm, making it suitable for many standard rack systems. Mounting is done to the front and/or rear profile rail, using the included mounting materials.

Mounting and installation
Mounting is done by breaking out the pre-punched mounting brackets and then securing to the front and/or rear 48,3 cm ( 19 inch ) profile rail. The exact number of required screws, washers and cage nuts depends on the chosen installation depth: 4x elements are required for 150 mm and 250 mm depths, while all 8 elements are needed for 350 mm depth.

Operational advantages
The shelf base provides a stable, flat base for devices that cannot be directly mounted to rack rails. The perforated surface ensures good ventilation, supporting cooling of devices mounted below. The maximum load capacity of 80 kg at an installation depth of 350 mm allows mounting of heavier devices. The simple installation via break-out mounting brackets and included mounting materials reduces installation effort. The black color (RAL9005) ensures uniform visual appearance in the server room. Compatibility with cabinets from 600 mm depth makes it a universal solution for many rack systems.
