Window won't stay open




Hello, thank you for posting,
Please start by reviewing the style and dimensions of the 15-087 coil housing to see how it compares to your original. This part is compatible and houses the Series 180 coil springs. The original coil spring should have a number stamped into the metal that indicates the weighted option needed.

For the window lock, are you able to show us a top down view? Can you also provide the distance between the installation holes from center to center? Thank you!




Unfortunately we cannot confirm based on the dimensions. The window sash will need to be removed and placed on a bathroom scale. Please provide the weight to move forward. Thank you!
