Replacement channel balances for Hurd double hung tilt windows pre 2005. Might you be able to assist me with these parts?

Hello,

I do not believe that we carry an exact match for your balance assembly but we do offer a similar setup for your Hurd windows. I'd recommend starting by removing your pivot shoe to confirm that it measures 1" wide like our 15-167.

The balance would be our S770-35, which is screwed at the top and uses the 15-043 terminal clip to anchor the pulley to the pivot shoe. The spring strength option would be 35D based on your original stamp, which will support a sash between 27-32 lbs. Look over these parts and see what you think. Thank you!
