Thanks for contacting us, Jeffrey. I see that you were looking at our S350-16 channel balance as a possible replacement for your part. It does show similarities to yours. Carefully compare your nylon attachments to ours to confirm this is a match. As for the option, since your stamping does not correspond to any of our options, the only way to choose the most accurate option would be to weigh your sash on a scale and correspond the weight number to the sash chart located on the product page. If you should have any further questions, please let us know. |
