Through-Wall Sights
For Clear Liquid
For Dark Liquid
Mount these sights from the inside of your tank and secure with a lock nut. They install through unthreaded holes in tank walls.
Sights for dark liquid have a reflector that makes liquid easy to see, especially in low-light conditions.
303 stainless steel sights are more corrosion resistant than aluminum sights.
