SWISCO - The Replacement Hardware Authority

Constant force balance id

A home owner from Fresno, California says:
This balance came from an Anlin single hung window. The measurement of the sash is 40 x 27 inches.
The only markings found on the balance are (7+7) Not sure what they mean. The measurements of the part are 9/16 and 1 1/4. Just like the ones in your images. I am also going to need the pivot bar which are 2 7/8. I will need enough balances for 5 windows and only 2 pivot bars. Thank you

Please see our Series 140 balance system. I think this can replace what you have. I recommend replacing your tilt bar as well, though. I don't think your old ones will work with the new balance. See our 26-405 for one possible match. Just make sure the hole pattern is the same.
