"This hook snapped soon after installation. I was looking for a strong hook, so chose the one with a stainless finish, thinking it would be stainless steel. When it has snapped, it was clear that the hook is actually made of plated brass.
Having said all the above, the local branch staff exchanged the broken hook for a new one with no fuss.
Hoping the old one had a manufacturing defect and the new one will perform as expected."
