Need help identifying window channel balance

A quick learner from Orlando, Fl says:
Hi.

I need two 1/2" window channel balances 30" long. Please see the attached pictures. There is no part number on the balances and other than the information below there is no manufacturers name on the Windows.

There are two stickers on the window. One says Series Mark40/50 SH W.B., AAMA /NWDA 101/I.S. 2-97, H-LC35*-114x78 (MULL)

The other says H-R35-53x77 (MUNT)

The window itself is about 49"x60".

Thanks, Phil

Thanks for posting, Phil. Start by looking at our S380-30 channel balance. This could be a good match, just go over our information to confirm that everything matches up.
