QNAP RAIL-A03-57

The QNAP RAIL-A03-57 is a slide-rail kit that lets you mount a 2 RU or 3 RU QNAP server securely in a standard 19 inch rack. Designed for models such as the TS-879U, TVS-EC1680U, and REXP-1220U, it provides a straightforward way to install or service your hardware without wrestling with fixed shelves.

The rails adjust to racks with mounting post depths from 22.8 to 34.4 inches, so they fit a wide variety of cabinets in data centers, colocation facilities, and office server rooms. A load capacity of 125.7 lb (57 kg) keeps fully populated chassis stable, while the 19.1 inch front panel width and 18.3 inch center-to-center post spacing line up with common rack standards.

Installation is smooth because the kit mates with 9.5 mm square mounting holes found in most modern racks. Once the rails are anchored, you can slide the server out for drive swaps or upgrades, then push it back in until the latches click into place, saving time during routine maintenance.

Manufactured in Taiwan under QNAP quality control, the RAIL-A03-57 offers a reliable, purpose-built solution for anyone who needs organized, accessible, and secure server placement.

We act solely as a reseller. Any product warranty is provided and administered by the manufacturer, not by our store. That means eligibility, coverage, and outcomes are determined by the manufacturer’s policy for each brand and model. Before purchasing, we recommend reviewing the warranty terms on the manufacturer’s website or in the product documentation to confirm what is covered and for how long.

If you need warranty service, please file the claim directly with the manufacturer. They may require proof of purchase, the product serial number, original packaging, photos, or basic troubleshooting. Some brands ask you to register the product or obtain a case number before shipping it for repair or replacement. We don’t submit or approve claims, but we can point you to the correct support links and contact details.

Keep your invoice and packaging in a safe place, and report any functional issues to the manufacturer as soon as they appear. If you’re unsure whether a problem is covered, the manufacturer’s support team can confirm next steps and timelines. While we cannot intervene in decisions or outcomes, we’re happy to provide purchase documentation or guidance so you can move through the warranty process smoothly.
