Channel Balance Replacements

Thanks for your photos. Based on what I see here, you have either our S380-23 or S385-23, 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.

Based on your sash weight of 31.5 pounds, I would also recommend the 2265 stamp option, which carries 30 through 34 pounds. 

Comparison of the S378, S380 and S385 balance shoes.

Great! You can review pricing on the S385-27 store page, linked to above. All of our balances come fully assembled and ready to install out of the box.

I'm afraid I don't know what sash cams or balance caps you need. I would need photos of each in order to make a recommendation.

Sorry for the confusion.  I was going off of your original statement of having a 2290 stamp. For a 27" long metal channel and a 31.5 pound sash, you want the 2660 option.

You can see a chart on the S385-27 store page that tells you exactly how much weight each option supports. In the case of the 2660, that's 30 through 33 pounds.
