## Long description

ProBase FS-1U-55 is a 1U rack shelf with a nominal width of 550 mm, designed for installation in standard 19-inch server racks. The shelf offers an adjustable mounting depth from 400 mm to 700 mm, enabling compatibility with a wide range of rack cabinet depths. It provides a stable, flat platform for devices that do not have front rack ears or that require additional support, and helps organise equipment and cabling in wiring closets, server rooms and equipment cabinets.
Advantages
The adjustable depth mechanism allows the shelf to fit racks with varying internal depths without additional hardware modifications. Constructed from rigid sheet metal, the shelf gives even load distribution and lateral stability for compact network appliances, small servers, power distribution units and peripheral devices. The 1U height footprint preserves valuable vertical rack space while offering a dependable mounting surface. The open front and rear clearance simplify airflow and cable access.
Suitable for
 Mounting small servers, network switches and routers that lack full rack ears
 Placing UPS modules, PDUs or battery packs in the rack
 Holding monitoring equipment, KVM extenders, media players and other peripherals
 Temporary equipment staging during maintenance or installation work
Key specifications
 Form factor: 1U height, 19-inch rack compatible
 Shelf width: 550 mm (nominal)
 Adjustable mounting depth: 400–700 mm
 Material: rigid sheet metal construction
 Load support: designed for compact devices and peripherals (check device weight against rack shelf rating)
 Front/rear clearance: open design for cable routing and airflow
How to use
Install the shelf into a compatible 19-inch rack by aligning the adjustable mounting brackets with the rack’s vertical posts and securing with rack screws or cage nuts appropriate for the cabinet. Set the depth to match the rack’s internal dimension between 400 mm and 700 mm before final tightening. Place equipment centrally on the shelf to distribute weight evenly and route cables through available openings for clearance. Verify that the combined weight of mounted devices remains within the rack shelf and cabinet load limits.
Usage recommendations
For reliable operation, confirm rack depth and mounting hardware type before installation, and use appropriate fasteners and, if required, supplementary support for heavy or long equipment. Keep airway paths clear to maintain ventilation, and periodically inspect mounting points and fasteners for secure attachment.
