Need HELP identifying parts for WindowMaster Non-Tilt windows

Question

We have 22 WindowMaster windows that we need to replace balancers in them. We bought this house a few years ago and many of the windows cannot even open anymore.

Pictures above are what the top and bottom pieces look like.

CAN YOU HELP us identify which parts to order? We weighed and measured everything.

We need balancers for the following:

1. Qty 13 windows - measurements: Width of Balancer 1/2"; Length of Balancer 30";

Width of Shoe 1-3/32" ; Weight of window 25lbs.

2. Qty 2 windows - measurements: Width of Balancer 1/2'; Length of Balancer 30";

Width of Shoe 1-3/32" ; Weight of window 16lbs.

3. Qty 5 windows - measurements: Width of Balancer 1/2"; Length of Balancer 22" ;

Width of Shoe 1-3/32" ; Weight of window 14lbs.

4. Qty 2 windows - measurements: Width of Balancer 1/2"; Length of Balancer 21";

Width of Shoe 1-3/32" ; Weight of window 10lbs

Any assistance you can provide in regards to which parts we need, would be GREATLY appreciated!! We have tried calling so many places, and NO ONE is willing to help.

If you cannot help, do you have any suggestions WHO WE CAN contact to get this info?

Thank you very much.

Hi Alexis. Fear not, I'm confident we can help. First, let's be clear on a few details. By 'width' of the bottom shoe, do you mean the 'heel-to-toe' measurement, or what we call the depth? And do all these sets of balances have identical attachments? If so, our Series 385 Channel Balance has a shoe depth of 1-3/32", so then I'm confident this is the balance you need.

Next, for the balance lengths, are you measuring just the metal channel, and not including the nylon fittings at either end in the measurement? If not, please re-measure the lengths without including the fittings. If you already did this though, and if you indeed have Series 385 Channel Balances in all these windows, I can tell you right now the balance lengths you'll need, as well as the stamp option. The stamp option indicates the weight range the balance is calibrated to support. Be sure your reported weights are accurate and precise.

For the 30" balances for windows that weigh exactly 25 pounds, use the S385-30. Choose a stamp option of 2940.
For the 30" balances for windows that weigh 16 pounds, use the S385-30. Choose a stamp option of 2930.
For the 22" balances for 14 pound windows, use the S385-22. Choose a stamp option of 2130.
Finally, for the 21" balances for 10 pound windows, use the S385-21. Choose a stamp option of 2020.

Let me know if you have any other questions.
