SIMONTON LH DBL HUNG WINDOW "SPRING ASSY"

A quick learner from Siloam Springs, AR says:
I am searching for the LH spring assembly for a double-hung Simonton window. The part number on the broken spring is: #4.0 35" P.

Hopefully this is adequate nomenclature to get us headed in the right direction?

Thanks.

It's hard to say. The stamp on the spring tells me how strong it is but not the exact type. Now, that said, Simonton windows have been known to use our 15-111, which in turn works with our Series 160 coil spring. Carefully go over this hardware to confirm that it matches yours.
