Rack shelf Stalflex S-RSF19-1U-170G 19" 1U 170 mm gray

Stalflex S-RSF19-1U-170G is a 19" 1U rack shelf with a depth of 170 mm in a gray finish. It provides a stable, low-profile platform for non-rackable equipment and accessories inside 19-inch server and network cabinets. The shelf is intended for mounting small devices, power supplies, tools or cable organizers where a full rack unit device is not required or available. Its compact depth helps maximize usable space in shallow cabinets and simplifies equipment arrangement for maintenance and cabling.

Advantages

The shelf offers a compact 1U form factor and a 170 mm depth that suits shallow racks and enclosures. Constructed for secure mounting in standard 19-inch rails, it delivers steady support for lightweight and medium-weight items while keeping a low profile. The gray finish provides a neutral appearance that integrates with common server-room and network-cabinet interiors. Installation is straightforward and enables flexible placement of non-rackmount components without permanent modification to the rack.

Suitable for

• Small network appliances and single-board computers
• External power supplies and UPS modules
• Patch panels, cable management tools and accessories
• Hand tools and maintenance equipment kept inside the cabinet

Key specifications

• Form factor: 19-inch, 1U height
• Depth: 170 mm
• Finish: gray
• Mounting: compatible with standard 19" rack rails
• Intended load: support for small to medium-weight components (see manufacturer guidelines)

How to use

Install the shelf by aligning its mounting holes with the 19-inch rack rails at the desired U position and secure it using appropriate rack screws or cage nuts. Place devices or accessories on the shelf, ensuring even weight distribution and that loads do not exceed the shelf's recommended capacity. Route cables to avoid obstructing airflow or access to other rack units. For safety, periodically check mounting fasteners and the condition of the shelf after installation and during routine maintenance.

Usage recommendations

Use the shelf for items that lack rackmount brackets or that require temporary placement. Avoid placing excessively heavy or vibrating equipment on the shelf. Combine with cable organizers and front or rear support brackets for extended items to maintain stability and proper cable routing.
