Customer needs 2 new balancers for single hung window. Manufacturer is unknown. Age of window may be 25-30 years. Balancer on right side (looking out) was missing when they purchased the house. Left side is still installed in window

Thanks for reaching out to us, Doug. We're happy to look into this but I'm afraid your photos don't help us ID the balance. Can you show us how the balance attaches to the pivot shoe? We would also like you to confirm the stamp and the metal channel length, as well as how the balance installs at the top of the window track.

Sounds good, Doug!

Good morning...new photos added showing the pivot shoe and the end of the balancer. The number stamped in the metal is C3340. The length of the metal is 33". The balancer installs at the top with one screw. I can provide additional photos if necessary.
Thank you

Thank you very much! Based on your photos, I recommend you have a look at the S770-33. This uses a terminal clip to attach to the pivot shoe like your old balance. Your 3340 stamp doesn't match any of our options but it may translate to the 33D stamp option. A pair of balances with this stamp will support a sash weighing 25 to 30 pounds but you could always weigh the window sash to confirm. 

As for the pivot shoe, the 15-152 comes to mind. Take a look and see if the specifications match what you need.

Please let us know if you have any questions!
