The Hoffman EDR23FM51U is a 2-post open frame rack constructed from aluminum with a black polyester powder-coated finish. It measures 96.00 inches in width, 24.25 inches in depth, and 15.00 inches in height. The unit supports 51U of vertical mounting space within a 23-inch standard width profile. It holds UL 1863, CUL, and CSA C22.2 approvals for safety compliance.
Verify the specific manufacturer designation, as nVent acquired Hoffman Enclosures. Confirm that the part number EDR23FM51U corresponds to the 2-post configuration rather than the 4-post variant. Ensure the required height and depth dimensions align with the installation site constraints before finalizing the order.
Select this model when a lightweight, cost-effective solution for telecommunications gear is required. The 2-post design offers easier access compared to enclosed cabinets. Verify that the 15-inch depth accommodates the deepest components in the intended setup. Check if additional shelf kits are needed for non-rack-mounted devices.
This component belongs to the Hoffman Open LAN Rack series, which provides standardized mounting solutions for network infrastructure. These racks are engineered to organize server and communication hardware efficiently. The series typically includes various heights and post configurations to suit different facility requirements.
Consult official nVent Hoffman documentation for direct cross-reference part numbers. Verify compatibility with existing mounting hardware and cable management accessories. Ensure replacement units maintain the same UL/CUL/CSA safety certifications.
