Tripp Lite SR3UCAGE

Overview

The Tripp Lite SR3UCAGE is a hinged standoff security cage designed to protect sensitive rack-mounted equipment within any EIA-standard 19-inch cabinet. It occupies 1U of rack space and creates a secure barrier around switches, patch panels, and other shallow devices, preventing unauthorized access to ports and buttons. Its perforated steel construction ensures proper airflow to keep equipment cool while maintaining visibility without opening the cage.

Ideal uses and environments

This security cage is well suited for environments where physical protection of network equipment is essential, such as offices, classrooms, retail counters, and branch closets. It works effectively in shared spaces where preventing tampering or accidental disconnections is a priority. The design fits well in data centers or smaller network racks where space and airflow must be preserved while adding a layer of security.

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.
