window channel length

Thanks for contacting us. When measuring your channel balance, you want to make sure that you are measuring the metal portion of the balance only. I am going to place a tutorial video for your review below that may offer some additional assistance with your balances. If you would like for us to help locate a replacement, I invite you to send us some photos of the balance removed from the window. Be sure to include measurements, and any stampings/markings you may find on the actual balance.
