Bridge a 4" Storz supply line to a 2.5" BAT coupling with a single machined adapter — the connection for stepping large-diameter supply down to a standard attack line. The Storz end matches the 115 mm lug-to-lug spacing common on 4" fire supply hose, while the BAT threads are the standard for 2.5" hose across BC and Alberta. Built from 6061-T6 aluminum with a hard-anodized black finish, it stands up to repeated field use and corrosion without adding bulk. Thread markings are laser-etched, so they won't wear off the way stamped or printed labels do.
