Channel balance help

Thank you for posting. Have a look at our S380-17 channel balance. This comes complete with a 19-005 balance top and 15-005 bottom balance shoe. Carefully compare your nylon fittings with ours to see if this balance is a match. Since your stamping does not correspond to any of ours, you will need to weigh your sash on a scale and refer to the sash weight chart listed on the store page. Get back to us if any questions or concerns come up.

Sure thing! That looks like a match for our 18-180. I recommend reviewing our dimensions just to be sure.
