I have a channel that needs to be replace , from my research I need a S377-24 , the sash weights 25lb. The broken channel is labeled 23D as in the picture, but on you website I didn't find it. I only saw the option 2350. Can I use option 2350 to replace the 23D?

A stamp of 23D usually corresponds to our 2340 option, not 2350. However, seeing as how your sash weighs 25 pounds, the 2350 would definitely be the better choice. Did you ever find your balance was weak?
