27 B and 33B

We can supply this balance for you, but it may need to be a custom order due to the hook at the top. Before I say anything for sure, can you show me a photo of the hole where the hook installed? That may change the configuration we go with depending on what kind of hole is used.

I'm afraid not, that's just the hook. I need to see specifically the hole in the window frame where that hook installs.

I understand that it hooks into a slot. As requested in my first response, I need to see a photo so that we know the best way to proceed with this order. There are many different kinds of slots and the design of this one will determine whether your balance has to be a special order or whether we can sell you a stock item.
