Installation and setup

The URK1U rail kit ships as a two-piece set with inner and outer rails that slide to the desired depth. Installation involves adjusting the rails to match your equipment’s depth, tightening a few screws, and securing the rails inside the rack. This straightforward process minimizes downtime and is ideal for environments where hardware changes happen frequently.

It suits IT professionals who need a reliable mounting solution for 1U devices such as network switches, small servers, and appliances that may not have built-in rack ears. The option to add a shelf expands its usefulness for non-standard equipment.

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.
