    316L stainless steel sights are more corrosion resistant than 304 stainless steel sights.
    With Screw-Together Window—Sights with a screw-together window make it easier to access your tank and clean the window than sights with a bolt-on window. To install these sights, place the body in a hole on your tank wall and weld it. Then twist on the window and tighten with a spanner wrench.
    DIN 11851—DIN 11851 rated sights meet dairy fitting standards.
