COIL SPRINGS - Empire Pacific Window

A contractor from Fairfield, CA says:

How do I find out the poundage? I know this came from a Empire Pacific Window. They are double hung tilt coil springs.

Thanks for posting, Michelle. Please see our 15-175 pivot shoe, Series 152 coil spring, and 15-150D housing. The 15-150D isn't exactly the same as yours but I think it can still work. Let me know what you think!

Hi Paul,

How do I know what poundage to order?

Thank you!

The coils should be marked with a pound rating code! If not, weigh the window sash and divide the weight by the number of coils per sash.
