ESDR19FM45U

Overview

The Hoffman Enclosures Inc. ESDR19FM45U is a seismic-rated, 2-post open frame rack designed for floor mounting in environments subject to vibration or seismic activity. Constructed from steel with a black finish, it features nominal dimensions of 84 inches in height, 20.25 inches in width, and 15 inches in depth. The unit accommodates 19-inch rack-mount equipment and includes side rails tapped on both sides with 12-24 UNC threads to facilitate the quick installation of components.

Feature Summary

• Seismic design engineered for stability in areas affected by vibrations and seismic activity
• Fully welded construction provides maximum rigidity and structural integrity
• Side rails feature dual-sided 12-24 UNC threading for rapid component installation

Applications

• Data centers located in seismic zones
• Telecommunications infrastructure requiring vibration resistance
• Industrial control rooms subject to mechanical stress
• Network installations in earthquake-prone regions

Procurement Notes

Verify that the specific project requirements align with the 2-post configuration and 19-inch compatibility before ordering. Confirm that the seismic rating meets local building codes and regulatory standards for the intended installation site. Ensure adequate floor space and load-bearing capacity are available to support the steel structure. Cross-reference the 12-24 UNC thread specification with existing hardware to guarantee compatibility with planned equipment mounts.

Selection Notes

Select this model when seismic certification is mandatory for the deployment environment. It is suitable for facilities requiring robust, floor-mounted support for 19-inch gear without the enclosure of a full cabinet. Consider the 15-inch depth constraint against the physical dimensions of the installed equipment. This unit serves as an alternative to 4-post racks where lateral stability is provided by other means or where cost efficiency is prioritized over full perimeter support.

Part Context

This product belongs to the Hoffman Seismic Open Frame Rack series, which specializes in providing secure mounting solutions for critical infrastructure in hazardous environments. The series distinguishes itself through fully welded steel construction and specialized seismic ratings. The ESDR19FM45U represents the 2-post variant within this lineup, offering a balance between structural security and accessibility for network or industrial equipment.
