Replace broken coil balance

Question

I am looking to replace the broken coils. have the 10j stamped on my coil. Certainteed is on the pivot shoe. I noted in the Q&A section the following "you will need to use an S170-405 and S171-405 on each side to replace the originals since we do not carry 10-pound strength". If that is your recommendation, I need to put 2 coils on left and 2 coils on the right?

Thank You,
Dave

Hello,

I agree that your photos resemble the Certainteed 15-192 pivot shoe that uses the S170 and S171 coil springs, along with the parts listed under the related items section of the 15-192 product page. To replace your 10 pound coils, you're correct that you would use one S170-405 and S171-405 on each side. We also offer the 15-156 cover and 15-157 drum to support the coils.

Please note that some customers have reported that they needed to shave the front of the shoe down to install it in their window jamb. Thanks for posting!
