Help finding the correct channel balance for Single Hung PGT-4000 window please.
(Window model number PGT 6SHSTKR)
Existing channel balance is stamped with 25 5 BSI RN
Channel measures 26" long and width 9/16"
I understand that I will need the weight of the sash to make the final choice but if you can get me started on the general part number, then I will select the matching weight once I weigh the sash. Thanks!!!
