Hello,
Your photos resemble the 15-087 housing pivot, which uses the Series 180 coil springs. If the sash weighs exactly 18 pounds, you can use one S180-09 coil on each side. Take a look and compare the specifications below and the accessories related on our product pages to yours. Thanks for posting!
