The existing channel balance does not have a number stamped on it. Print info say " 29 3 HR CALDWELL" ? Does this relate to a specific replacement part. Sash weight around 32 lbs. Also have smaller Kinco window with 18" lower sash, with around 16" channel balance. Do you have that replacement part? Need arourd 8 of the 30 ",and 4 of the 16" balances.
Thank you,
Bill
