Seismic-rated 42U enclosure for IT environments

The Tripp Lite SR42UBZ4 is a 42U, 19-inch server rack cabinet built to meet Zone 4 seismic requirements. It is intended for secure, high-density server and networking deployments in data centres and IT rooms where structural resilience is mandatory. The unit ships fully assembled to accelerate deployment.

EIA-310-E square-hole rails

Vendor-neutral square-hole mounting rails accept the included 50 M6 cage nuts and 50 M6 screws, guaranteeing compatibility with all EIA-310-E compliant 19-inch equipment. Toolless mounting slots allow quick installation of PDUs and vertical cable managers. Lightweight modular doors and side panels provide safe, convenient service access, while integrated baying tabs enable row configurations.

Zone 4 rating and airflow design set operational

Perforated front and rear doors deliver massive front-to-rear airflow, supporting hot-aisle and cold-aisle layouts. The enclosure meets all cabinet requirements towards PCI DSS compliance. Buyers needing a non-seismic rack, a smaller U count, or a wall-mount form factor despite the 353.00 lb weight should consider other solutions.
