19" rack depth extension VALUE 26.99.0422 — extension depth 151.5 mm

VALUE 19" rack depth extension model 26.99.0422 increases the usable mounting depth of standard 19-inch racks by 151.5 mm. The extension is intended to provide additional rear clearance for servers, switches, PDUs and other rack-mounted equipment without modifying the rack's main frame. It is a fixed-depth, compact solution that supports improved cable routing and better accommodation of deeper devices in existing rack enclosures.

Advantages

This rack depth extension delivers a stable, non-adjustable increase in mounting depth that simplifies installation of deeper IT components. Constructed for compatibility with standard 19" mounting rails, it helps prevent interference with existing rack structures while offering a neat and compact footprint. The extension supports organized cable management at the rear of the rack and reduces the need to replace the entire rack when additional depth is required.

Suitable for

• Adding rear clearance for deeper servers and storage units
• Installing network switches and PDUs that require extra depth
• Retrofitting existing racks to fit new equipment without replacing the rack frame
• Improving cable routing and access behind rack-mounted devices

Key specifications

• Compatible with 19" rack systems
• Extension depth: 151.5 mm additional mounting space
• Fixed-depth design for stable equipment support
• Compact form factor to minimize footprint impact
• Material and finish suitable for standard server room environments

How to use

Mount the extension to the rear section of a 19" rack by aligning it with the rack's mounting rails and securing it with appropriate fasteners. Position rack-mounted equipment so that the additional 151.5 mm clearance accommodates rear connectors and cable runs. Verify that the extension is firmly attached and that equipment weight is within rack load limits. After installation, route and secure cables to maintain airflow and service access.

Usage recommendations

Check equipment depth and rear connector locations before installation to confirm the 151.5 mm extension provides sufficient clearance. Use compatible mounting hardware and, if necessary, consult rack load specifications to ensure safe weight distribution. For optimal cable management, combine the extension with rear cable guides or horizontal organizers.
