Hello,

This looks like our S140 coil assembly. You'll need to weigh your window sash to choose the correct strength option,. Thank you!

Based on the weight of your window sash, I would recommend using our S140-5 on the left and right sides of the window, which will support a sash between 9-10.99 lbs. Thank you!
