Hammond 44U Zone-4 Seismic 2-Post Open Frame Floor Rack

The Hammond 44U Zone-4 Seismic 2-Post Open Frame Floor Rack (DRZ4 Series) is a high-strength, telecom-grade rack solution engineered for mission-critical environments where structural stability and seismic compliance are essential. Designed to meet GR-63-CORE Zone 4 seismic standards, this rack is built to withstand the most demanding earthquake-prone conditions while maintaining full operational integrity.

Constructed from heavy-duty welded steel, this 44U open frame rack supports up to 2,000 lbs of equipment load, making it ideal for dense telecom, network, and server deployments. The 2-post design provides a compact footprint while still allowing for flexible mounting of patch panels, switches, and lightweight server equipment.

With EIA-compliant 19″ mounting rails and 10-32 tapped holes, the rack ensures compatibility with standard rackmount equipment. The open frame architecture promotes maximum airflow, easy cable routing, and simplified equipment access, making installation and maintenance faster and more efficient.
