19" rack depth extension VALUE 101.5 mm for server racks 26.99.0421

VALUE 19" rack depth extension 101.5 mm (model 26.99.0421) adds 101.5 mm of mounting depth to standard 19-inch server racks. The extension is intended to increase usable rear-to-front space inside data cabinets and telecom enclosures, enabling installation of deeper servers, switches, cable managers or other rack-mounted devices. It is compatible with conventional 19" rack rails and designed for straightforward integration into existing rack frames without altering the primary rail geometry.

Advantages

The depth extension provides a compact, standardized way to gain additional mounting depth while maintaining the rack’s original footprint and stability. Installation simplicity reduces downtime and effort during retrofits. By extending the usable depth, the accessory supports cleaner cable routing and better accommodation of equipment that would otherwise extend beyond the existing rails. Constructed to match typical rack mounting dimensions, it preserves alignment with front and rear mounting points.

Suitable for

• Adding space for deeper rack-mounted servers and switches
• Improving cable management and routing behind equipment
• Retrofitting existing racks to accept non-standard or deeper devices
• Installing vertical PDUs or accessory brackets that require extra depth

Key specifications

• Additional mounting depth: 101.5 mm
• Form factor: compatible with standard 19" rack rails
• Application: server racks, network cabinets and telecom enclosures
• Material and finish: manufactured to match common rack construction and surface treatments for durability (meets standard mechanical requirements for rack accessories)
• Mounting orientation: rear extension that preserves front rail positions

How to use

Mount the depth extension to the rear of the existing 19" rack rails following the rack manufacturer’s instructions. Align the extension so that the additional 101.5 mm of depth is added uniformly across the rack unit positions, then secure it with appropriate rack screws or fasteners. After installation, verify that mounting holes align with equipment ears and that the extension is firmly attached to maintain rack stability. Route cables and position equipment taking advantage of the extra depth to avoid strain on connectors.

Usage recommendations

Check equipment depth and required clearances before installation. Use compatible fasteners and, if necessary, reinforce attachment points when installing heavy devices. Follow standard safety procedures for working inside racks, including powering down equipment when appropriate and ensuring weight distribution remains within the rack’s rated capacity.
