Window Ballast replacement for Kensington Windows

Question

I am hoping you can identify this part. The track holding the ballast is very narrow and will need to be pry open to replace.

Hello,

We can't be sure with the hardware still installed but your photos resemble the 15-087 housing pivot, which uses the Series 180 coil springs. Note that the 15-086 tandem housing is required for the second coil. Take a look and compare the specifications below and the parts related on this page to yours. Thanks for posting!
