Which parts should I get?

Question

Good day,
I need all the window balancer hardware for a window. I have taken pictures of an identical window's parts to try and help.

I know I'll need 2 of the giant springs, What does 28D BS1 RP mean? - Which balancer would you suggest?

The width/depth of the balancer is 1/2 inch.

The end of the balancer hooks on to a metal hook/S-Hook which I need, but I do not know what it looks like or what it would be called to search.

I would basically need a set for each side of the window.

Any help with this would be great!
Thank you.

We can replace this balance, but it will have to be a special order. Basically we'll use our S770-28 channel balance with a 28D stamp and with a rivet installed in the top hole. The S-hook is sold separately and would be either our 19-029 (short) or 19-030 (long).

The 28D stamp indicates how much weight two balances working together can support. Specifically, 28D means these balances can carry 23 through 28 pounds. You may want to weigh your sash on a scale to confirm that it falls in that range.

In the meantime, I'll email you a special order link and price quote for 2 of these right now. Let me know if you wanted to change any of these details.
