Hi Could you please help me to find replacements for my 15" block and tackle window balances?

I would greatly appreciate any help you may be able to render

Best Regards,

I would consider our S385-14 channel balance. Based on your stamp, the metal channel should be 14" long, not 15". I would double check that just in case.

Thank you Paul.
You are correct the metal part does measure 14".
I included the plastic ends when I initially measured them!

How do you determine the weight for the spring option to place the order?
Thank you in advance.

Your stamp "13 4" normally translates to 1340
To check, remove and weigh your window sash; a pair of 1340 will carry a window sash weight range of 11-12 pounds.

Hi Donna,
I just weighed my sash and it only weighs 7 lbs!
I checked this against another scale.
I called Swisco and the gentlemen I spoke with said a 1320 was necessary to carry the 7 lb sash.
I do not understand why the balance stamp in my photo clearly show "13 4" which you indicate translates into a 1340 balance which you say carries an 11-12 lb sash when the window only weighs 7 lbs??? Could you be mistaken?
Thanks
Jeff

I'm not sure either. It's possible whoever installed these balances to begin with installed the wrong ones. You can see the chart on our S385-14 store page that shows you how much weight each option can carry. This information comes from the factory itself, where these springs are calibrated, so I promise they are accurate.
