need help replacing window balance

Hello,

We'd be happy to help but your balances will need to be a custom order since they use the 15-224 inverted link and the 15-198 hook attached to the end of the pulley cord, which does not come with the stock S795 channel balance (37D) that we'll use as the base for your replacements. We'll just need to know the number of balances that you need, with the minimum being two, to send over an order link and price quote. We also offer the 15-216 pivot shoe shown below that is commonly used with the 15-224 inverted link. Thank you!

We do not recommend trying to use a different type of balance since the window manufacturers choose the hardware for their windows based on a variety of factors. Trying to modify something else to work for your window could cause damage or issues long term. 

The tension in channel balances is not adjustable but I can tell you that the 37D strength code on your original balance will support a window sash between 27-32 lbs. If you're not sure if the current balances had the correct spring strength, I would recommend confirming the exact sash weight to ensure that the fall within the supported weight range. 

Thanks for getting back to us. If the window sash weighs exactly 27 pounds, you could also use 37C strength options, which will support between 22-27 lbs. If you would prefer to go with the lighter strength option, just let us know and we will be able to send over your order link and price quote. Keep in mind that it is important to confirm the exact sash weight to ensure that the strength options that you choose will properly support the window. 

Unfortunately, we can't determine which weight range your sash would fall in based on photos. With that being said, we sent you an order link and price quote for the eight balances with the same 37D strength option as your originals. It is possible that your original hardware may just be older and in need of replacement. If you suspect that the balances were always too strong for the windows, weighing the sash would be the only way to confirm and is recommended since these custom balances are not eligible to be returned for a refund.
