I found that it can be difficult to find something as simple as this finial. I thought it would be available from a lot of different vendors. Well things like this are available, but in many cases, at ridiculously exorbitant prices (like $38!). So I ordered this one and it came quickly and fit just perfectly and had the added bonus of looking good.
hard to find
Yours is the only store that I found what I was looking for.The handles are what I needed.
