Hammond 44U Seismic 2-Post Open Frame Floor Rack

The Hammond 44U Seismic 2-Post Open Frame Floor Rack (DRZ4 Series) is a carrier-grade, heavy-duty rack engineered for high-risk and regulated environments where seismic stability and structural integrity are critical. Built to meet GR-63-CORE Zone 4 seismic standards, this rack is designed to maintain equipment uptime and physical stability even during severe seismic activity.

Constructed from reinforced welded steel, this rack supports up to 2,000 lbs of equipment, making it ideal for dense telecom, switching, and industrial network deployments.
Its 44U height (84″) and 22.75″ wide frame provide enhanced lateral stability—an essential feature in earthquake-prone environments.

The rack includes EIA-standard 19″ mounting rails with 10-32 tapped holes, ensuring compatibility with standard rackmount equipment while supporting both front and rear mounting configurations.
The open frame design promotes maximum airflow, easy cable routing, and full accessibility, making it ideal for high-density installations where cooling and maintenance efficiency matter.
