Eaton Tripp Lite Standard-Depth Server Rack Enclosure for Mission-Critical IT, 42RU

The Tripp Lite SmartRack SR42UB is a heavy-duty 42U server rack enclosure designed to house, organize, and secure standard-depth 19-inch rack equipment in server rooms, IT closets, edge computing environments, and micro data centers. Built from rugged powder-coated steel, this enclosure delivers exceptional strength, security, and airflow for critical IT deployments.

Secure and Accessible Equipment Housing

Reversible front and rear doors and removable side panels lock securely to help prevent tampering, theft, or accidental damage. Quick-release doors and panels provide fast access to equipment and cabling, while vented doors promote efficient front-to-rear airflow to keep devices operating at optimal temperatures.

Designed for Easy Installation and Deployment

The SR42UB ships fully assembled for immediate installation. Pre-installed casters allow smooth positioning through standard doorways, and adjustable levelers stabilize the enclosure once in place. Front and rear mounting rails support rack equipment up to 37 inches deep, and integrated 0U mounting rails enable tool-free installation of compatible PDUs and vertical cable managers.

Expandable and Standards-Compliant Design

Built-in baying brackets allow multiple enclosures to be joined in a row, with center-to-center spacing aligned to standard data center floor tiles. The cabinet provides the physical equipment and media security required for PCI DSS compliance, making it suitable for environments that process, store, or transmit sensitive payment data.
