Channel Balances 2420X, Tops & Bottoms

A home owner from USA says:

We would like to replace channel balances (stamped 2420X) for 4 windows (i.e., 8 balances). The balances are 25" long, and thus it appears to me to be Series 350 with 15-002 bottoms. The tops appear to be #19-004 or 19-031. Also, I need one take out clip #16-002.

Attached are photos of the tops and bottoms. Please tell me which tops to buy. Thank you.

Thanks for posting. Have you seen our S370-25 channel balance? This seems to have the same nylon attachments as yours. Check out out and see if you agree.

Yes, the S370-25 seems similar. Thank you.
