Balance

Thanks for posting. See our S751-14 Ribbed Channel Balance for Tilt Windows. Look over all the specifications listed on the product page to ensure this is the right match for you. Your stamp option of 13TG is unfamiliar to us. To know what stamp option to select, you should weigh your window sash. You can then match that exact weight with one of the weight ranges listed for each stamp option on the product page. Let us know if you have any questions.
