Compliance and Certifications

The DRZ4 Series 2-post open frame rack is engineered for mission-critical applications requiring certified seismic performance. Independently tested to Telcordia GR-63-CORE Zone 4 standards and UL2416 rated to 2000 lb, it delivers maximum strength and reliability in telecom and infrastructure environments.

Designed for central offices, data centers, and regulated installations, the DRZ4 provides open access, structural integrity, and secure deployment in the most demanding seismic conditions.

  • ■UL2416 listed rack (2000 lb load rating) ensures verified structural performance for high-capacity installations.
  • ■Independently tested and certified to Telcordia GR-63-CORE Zone 4 seismic standards ensures performance in the most demanding seismic environments.
  • ■Seismic rated to 800 lb dynamic load (with bolt-down kit) in accordance with GR-63-CORE supports deployment in regulated telecom and infrastructure environments.
  • ■TAA-compliant, manufactured in North America supports government procurement requirements and ensures consistent quality.
