Channel Balance

Question

Channel lengths are 29". The existing marking is 2820 but they are very difficult to push down (sashes are light). Need to know which series to purchase

Thanks for your photos. Based on what I see here, you have either our S380-29 or S385-29, 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.
