I need two replacement channel balances.

The original channel balance is stamped 27 4 FW CMC 10 (IMG_3474, 75, 76). I believe the correct one is the 28" Series 390 Channel Balance with the 2710 option? Also I need two top sash guides (IMG_3471 and 3472) which I can not seem to find.

Thanks,

Ted

Thanks for posting, Ted. I agree, the S390-28 looks like a good match. Based on your stamp, though, I'd go with the 2740 option. You can always weigh your sash to confirm. As for the top sash guide, I don't recognize yours. It's similar to the 18-008, though. Could this be a possible replacement? Carefully go over our dimensions and see what you think.

Thanks Paul, I'll go with the 2740 option. The 18-008 top sash guide is the correct width but a 16th shorter in depth. I think I can make it work though.
