DataComm or Harger Ground Bar Lightning protection assembly. 24 mounting holes with 2 insulator standoffs and bolt kit. New never used. I have 5 each kits, and I will sell them for $110.00 each, buy all 5 and I'll let them go for $400.00. Others sell them for $175.00 each. Great investment if you have a communications tower and you want to protect all your equipment from lightning...
