Channel balance

Question

Trying to order the correct channel balance. From the markings I know it is 2630 but not sure which series to order.

Also... not sure if these need to be replaced to solve my issue or not... the window sash is incredibly hard to open and close... does not glide. The channel balances seem to be intact and rated correctly for a 17 pound window

Thanks for your photos. Based on what I see here, you have either our S380-27 or S385-27, depending on the depth of the bottom shoe. That's the only difference between them. I recommend measuring your shoe and referring to our dimensions to confirm the best match.
