19" Rack Rails ROLINE 12 HE Model 26.21.0318 — mounting rails for 19-inch racks, 12U height

ROLINE 19" Rack Rails Model 26.21.0318 are mounting rails engineered for installation of 19-inch rack equipment with a height of 12U. These rails provide stable lateral support and alignment for servers, network switches and other rack-mountable devices in data centers, server rooms or network cabinets. The design focuses on compatibility with standard 19" racks and on simplifying installation and removal of hardware while maintaining secure mounting under normal operating loads.

Advantages

The rails offer consistent spacing and robust support for 12U rack-mounted equipment, reducing the risk of lateral movement and facilitating quick attachment and detachment of devices. Their standardized form factor makes them compatible with a wide range of 19" enclosures and devices, helping to streamline rack organization and maintenance tasks.

Suitable for

• Mounting 12U rack-mount servers and appliances in 19" racks
• Installing network switches, patch panels and UPS units compatible with 12U space
• Use in data centers, server rooms, office network cabinets and telecommunications enclosures

When it may not be suitable

These rails are intended for standard 19" rack systems and a 12U equipment profile. They are not suitable for non-standard or proprietary enclosures that do not follow 19" mounting dimensions. Heavy equipment that exceeds typical rack-mount load limits should be checked against the rack and rail load ratings before installation.

Key specifications

• Form factor: 19-inch mounting rails
• Height capacity: 12U
• Primary function: equipment support and alignment for rack-mounted hardware
• Typical mounting: front and/or rear rail attachment to rack posts
• Intended environment: data center, server room, network cabinet

How to use

Install the rails by aligning them with the rack's 19" mounting posts at the desired U positions and secure using appropriate rack screws or cage nuts compatible with your enclosure. Slide or mount equipment onto the rails, ensuring correct engagement and that device weight is supported by both front and rear attachments where applicable. Follow the rack and equipment manufacturer's guidelines for load distribution and fastening torque to maintain safe operation.

What to consider before purchase

• Verify that your rack uses standard 19" mounting dimensions and has available 12U of vertical space
• Confirm compatibility of rail mounting holes with your rack's post type (square or threaded) and required fasteners
• Check the weight of equipment to ensure the rails and rack can support it safely
• Ensure the rail length and depth match the depth requirements of your devices

Usage recommendations

For stable and safe installation, use matched fasteners and cage nuts where required, distribute weight across both front and rear mounting points, and follow the rack manufacturer's load limits. Periodically inspect rail attachments and fasteners for looseness after initial installation and during maintenance.
