Thank you for your patience during this busy season. I'm not immediately familiar with your balance, but I wanted to let you know that we're looking into it and hope to have an answer for you soon. Please bear with us a little longer as we continue our research.

Thank you for your patience while we looked into this. I unfortunately couldn't find an exact match for this balance. We carry a similar set up that may work for you, though. It would be our 15-252 dual support with two S160-5 springs. One of these set ups on each side of your window will carry a sash weighing 20 pounds.

Look over the dimensions and information we show for each product and see if this would work for you. You might also want the 16-032 mounting clip.
