Guage Hatches
4" (DN 100), 6" (DN 150) and 8" (DN 200) flanged to mate with 125# ANSI and DIN PIN 16 flat flanges
FM Approved. Series 4960, 4970, 4980 and 5960 are Factory Mutual Approved in all sizes
GREENDECK Hatches provide ready access to
storage tank’s interior for inspection, gauging and sampling.
Gauge Hatches are intended for use where the fire protection
afforded by a Protectoseal flame arrester is not considered
necessary.
The lockdown feature on the Series 4970 / 5960 makes them
particularly suited for use on tanks with normal operating
pressure under 3 PSIG. Tightening the thumb screw holds
the cover securely in place, thereby minimizing leakage and
evaporation losses.
