SWISCO - The Replacement Hardware Authority

Coil Spring ID

A handy person from Westwood, NJ says:
Can you help me please. My coil springs on my double hung window lower sash are broken.
Lower sash is 31.5" wide, 19.25" deep, 16lb weight. Stamped marking on coil could be either 10 or 19, I cannot tell. the Window has NO manufacturer identification on it. It is acrylic, and was installed about 3 years ago.
The spring width is 1/2".
Please see attached pictures.

Please see our 15-177 pivot shoe and Series 152 coil spring. I believe these parts match your pictured hardware.

Thank you. I ordered the 8lb ones.
