I'm having trouble identifying my springs. It's a 2 spring per side system, one is stamped E and the other F? Not sure how many pounds they are? I think I have almost everything else identified, looks like pivot arm 26-446 and coil balance shoe 15-175. I also need a couple of those bushings.
I believe the F spring (copper color) does have a 7 on it, it was hard to read. Now the silver spring with the E on it...
Thank you!

Thanks for writing in. I agree that this looks like the 15-175, and that your pivot bar resembles our 26-446; just confirm that the position of the pin that fits into the shoe matches, I believe you have the broken piece incorrect placed in your photos. Finally, this coil balance system uses our Series 152 coil springs. If there is a '7' on one of the springs, then you might need our S152-7, which supports 7 lbs individually. If you're uncertain about what you have, it's best to weigh your window sash. Give us that exact weight, and we'll out the rest for you. |
