Underground Enclosure Hardware
Tengco Can Supply 5G Hardware for Underground Enclosures
For over 40 years Tengco has supplied utilities products that can be manufactured to meet any specification, including IEEE C135.1-1999. One of our specialties is hardware for lightweight, molded polymer concrete box underground enclosures. Utility companies rely on underground enclosures to provide maximum strength and durability while being easy to install.
More than 800,000 new 5G transmitters and communication devices are expected to be installed across the United States by 2021, but many neighborhoods want to hide the additional cell towers and utility boxes needed to provide this service. One solution has been to install 5G transmitters and additional 5G hardware in underground enclosures and handholes.
Tengco has designed custom parts as well as standard hardware for the underground enclosure telecommunications and utility networks. At Tengco, we know that underground enclosure longevity and superior performance are absolute imperatives for telecommunication hardware, and you can be confident that you’ll receive the highest quality parts needed.
From global sourcing to product development, fabrication, inventory tracking, warehousing and shipping, we make sure that your order meets your exact specifications. Tengco can provide the quality, performance, and price customers require for their underground enclosure hardware.
With production and quality control facilities located both at-home and abroad, Tengco is positioned to be an ideal global partner for your underground enclosure hardware needs.
