Spring replacement question

A quick learner from Princetown, New York says:

I need both left and right spring assemblies. It is a double hung window. The lower sash is where these springs will go. The are 2 springs on each side even though the picture I sent only shows one. The lower sash is approximately 20 inches high and 30 inches wide. I'm not sure which springs to order. Can you help?

Starting with your pivot shoe, see if our 15-111 would make a good fit. These are used with the Series 165 coil spring. We will need to know the number that is stamped ion the coil spring. If there is not a number on the spring, we will need for you to get back to us with the weight of the window sash.

Thanks for the response. The number on the spring is 4.The 15-111 shoe looks just like mine. I think we're on the right track. What spring assembly do you recommend?

Take a look at our S165-4 coil spring. See if this would make a good match.
