Indicator Post Underground Type FGVI345
FIREGUARD FGVI345 Underground Indicator Post
The FIREGUARD FGVI345 is an FM Approved underground-type indicator post engineered for precise valve position monitoring across a wide range of pipe sizes — from 2″ up to 12″. Built with an ASTM A536 ductile iron body and SS304 stainless steel hardware, it’s designed to perform reliably in harsh underground conditions with minimal maintenance.

With a broad size range and straightforward four-step field adjustment, the FGVI345 suits a variety of fire protection installations from small distribution lines to large-diameter mains.
