What do I need for my Windows?

Hmm, sounds like you could be looking for tilt latches. If you can send us a photo of your removed from the window we can help narrow down your search!

Hm, OK, what you actually are showing us your pivot shoes and coil balances. We can certainly help you replace these. It looks like your lower sash uses our 15-199 Pivot Shoes, which are compatible with our Series 165 Coil Springs. Your Upper Sash uses our 15-180 Pivot Shoe, which uses our Series 190 Coil Springs. It's rather unusual for a window to use different coil springs in each sash; did you ever replace these pivot shoes or coil springs before? If not, and if it's been working this whole time, then it should be OK. Let us know if you have any other questions.

OK, great. Then it sounds like you need a new 15-180 and some new Series 190 Coil Springs. Check your old springs for stamps that indicate the spring weights you need. Let us know if you need help with this. 

You would have needed to remove the coil spring cover in order to determine whether or not there was a number printed on the actual spring. The numbers on the cover do not tell us anything about the weight of your sash. If there are some stamped numbers on the actual sash, [lease get back to us with that number. If there aren't any numbers on the coil, then you will need to weigh your sash and get back to us with that weight number. Thank you.

I'm afraid not. The stamp will be on the coil itself, not the cover. The only way to see it is to remove the spring from the window.

If you remove it and there is no stamp, give me the exact weight of your sash instead. I can then calculate what your weight rating should be. Those are the only two ways to know what strength springs are required for your window.

Nope, they sure don't. Believe me, I gotta deal with how these people design windows every day of my life. They would rather you buy a whole new window than just these individual parts. Obviously this isn't necessary, but it can be annoying. let us know if you have any other questions! We're happy to help as best as we can.

I can't quite make it out in your photos, but if there is a #5 stamped on the spring itself, then that would indicate that one of the springs you need is an S190-540. This supports a weight of 5 lbs. You'll need to see if you can locate the stamped numbers on the other springs you need to replace. If they're unavailable, you'll have to weigh your window sash. Like Tom said, we can then calculate the other spring weights you require. 

Sounds good. If you need anything else, just ask me.
