Here are a couple of pictures showing my concern about the replacement lower offs at Berowra.
This is the type of Stainless lower off used.
This is my concern with the notch.
As shown in the photo above, the wire gate does not 'lock' when closed, therefore the strength of the stainless bar is the only thing being relied upon.
These lower offs were purchased from a boating supplies shop, Bias Boating at Artarmon.
Sorry about the fuzzy image.
