Hi,
My bathroom window will no longer stay up by itself. I removed this hardware. Please let me know what part I need to replace it. Thank You, Victoria

Hi, Victoria! That looks like our 15-175 shoe and Series 152 coil spring. Check your old coil for a printed number, which tells you how many pounds the coil holds. You'll need that number to select which coil to get.

Hi,
I don't see any number on the part. Do you know which number would work for a small bathroom window? Thank You, Victoria

In this case, weigh your sash and we will come up with the spring weight number for series 152, 1/2" wide spring.
