Ventev's Flex-Line Universal Steel Enclosures are specifically designed to provide NEMA 4 outside protection with the enclosures with solid doors or NEMA 12 inside protection with the enclosures with windows. Each enclosure offers a clean, seamless design to protect wireless equipment from damage caused by tampering or environmental elements. These versatile, rugged enclosures are constructed from 14-gauge steel and include eight knockouts for antenna ports and one for a strain relief. Each knockout is only visible from the inside of the enclosure to enhance the outside aesthetic design, making them excellent, long-lasting enclosures for multiple applications and as users upgrade from an organization's existing wireless equipment to new technologies. Includes (1) 3/4" knockout for strain relief, (6) 1/2" knockouts for RPTNC connectors and (2) 5/8" knockouts for N connectors.
