Chieftec RSR-260 Slide Rail Mounting Kit - 19 inch - for UNC-410B-3R, UNC-410S-B, UNC-410S-W - Black

Data centre technicians and IT integrators often face the challenge of securely installing heavy server chassis into standard 19-inch racks. The Chieftec RSR-260 slide rail kit solves this by providing a robust, telescopic mounting solution for compatible Chieftec UNC-410 series chassis. This kit includes a pair of steel rails with a ball-bearing slide mechanism, enabling smooth extension and easy access to the chassis for maintenance. The rails support a maximum load of 30 kg and are adjustable to fit rack depths from 600 to 800 mm, ensuring a precise fit in most standard cabinets. A quick-release mechanism allows the chassis to be detached and reinserted without tools, streamlining hardware swaps and upgrades.

The quick-release feature saves valuable time during server maintenance, allowing technicians to slide the chassis out completely and remove it with a simple lever action. Built from durable steel with a black finish, it matches the aesthetics of most server rooms while resisting corrosion and scratches.

Ideal use cases

• Installing Chieftec UNC-410 series chassis in 19-inch server racks in data centres
• Upgrading existing fixed-mount chassis to sliding rails for easier maintenance
• Building custom rack-mounted server solutions for enterprise or SMB environments
• Replacing worn or damaged rail kits in existing Chieftec installations

Good to know

The kit includes all necessary mounting screws, so no additional hardware is required. It is designed specifically for the Chieftec UNC-410B-3R, UNC-410S-B, and UNC-410S-W chassis models; using it with other chassis may void warranty or cause improper fit. The rails are sold as a pair, sufficient for one chassis. For optimal performance, ensure the rack is properly grounded and the rails are mounted level. The black powder-coated finish is both functional and visually unobtrusive.
