Hi,

I recently ordered & received 2 window balances:
17" Series 351 Channel Balance
S351-17, option: 1620

I found I need to order a top sash guide & need to know the one to order. It looks like #18-008. Is that the right one?

Thanks,
Ken M.

Hi Ken,
Yes, the 18-008 could be the needed replacement, just compare the dimensions to one of your original top sash guides before ordering.
