Lightning Master Ultra Sharp Point™ air terminals meet the requirements of NFPA 780 and are UL 96 Listed. SRAT’s provide a zone of protection exactly the same as any other lightning rod, and are designed and intended to be used as components in a NFPA 780 or UL 96A system. A completed installation is eligible for a UL Master Label, the gold standard in lightning protection. In oil field applications, grounding requirements of the American Petroleum Institute API 545 and API 2003 are applied.
