Description
The Eaton Tripp Lite SmartRack SRN3RG12U is a rugged 12U industrial wall-mount enclosure designed to safeguard your critical rack-mount equipment from harsh environments. Built from heavy-duty powder-coated steel, it offers NEMA 3R protection against rain, sleet, snow, dust, and ice—ideal for indoor and outdoor use in factories, power stations, warehouses, and construction areas.
Its fully welded metal housing locks securely to prevent unauthorized access, while the sealed gasket door ensures reliable environmental sealing. Two top-mounted fans with a thermal switch automatically activate at 86°F (30°C) to maintain optimal airflow and protect equipment longevity.
The enclosure ships fully assembled and includes adjustable front and rear rails for equipment up to 23 inches deep with a 200 lb (90.7 kg) load capacity. Offering long-term reliability with a 5-year limited warranty, the SRN3RG12U delivers industrial-grade protection and performance for sensitive IT, AV, and networking equipment.
