I need to replace the channel balances in a couple of windows as the pulleys inside have broken. The windows have the same channel balances. Here are the details:

Stamp on channel balance: 30 3 CALDWELL FM
Channel balance dimensions: length 31" (without guides); depth 1/2"; width 5/8".
Top guide: width 15/16" (tab to tab); top width 9/16" (above tabs); total length 1-1/4".
Bottom guide: width 1" (tab to tab); width 9/16" (above tabs); total length 1-1/8".

The window information if needed:
Rollyson Aluminum Products
MFGR Code Y0-1
DH-C35
Series 2500

I've attached pictures of the top and bottom guides.

Please let me know the part number(s) so I can order new ones.

Thanks,
Steve Espeland

Take a look at our 385-31. Just make sure that the nylon fittings, particularly the depth of the bottom nylon shoe, match your old balances. You'd need a stamp option of 3030.
