NEMA 3R ENCLOSURE DESIGNED FOR PROTECTION AGAINST HARSH ELEMENTS: The SRN3RY12U protects its contents against the ingress of water (including rain, sleet, snow, splashing water and hose-directed water), solid foreign objects (including falling dirt and windblown dust) and even ice forming on the outside of the enclosure.

LOCKS SECURELY TO HELP PREVENT THEFT, DAMAGE AND TAMPERING: The fully welded steel housing locks securely with the included keys to protect its contents against theft, tampering, dust and other contaminants. The weather-sealed door swings away on a sturdy hinge, allowing easy access to equipment and cabling during installation and maintenance. Data and power cables may be routed through a bottom conduit cutout. EASY ENCLOSURE AND EQUIPMENT INSTALLATION: This 12U industrial enclosure comes fully assembled and ready to mount to the wall with user-supplied hardware. Front and rear mounting rails adjust independently to accommodate equipment up to 23 inches deep. Hardware for mounting equipment inside the enclosure is included.
