Replacdment Window Channel Balance

Question

Request review and ordering information; I did one of these, on a different window, earlier this year, it was a 25" Series 351, looks the same, but I'd like confirmation before I place my order...

Thank You.

The Series 351 does look close, but that's all I can say based on these photos. The deciding factor will be the depth of the bottom fitting; if it's 1", then the Series 351 is what you want. However it may also be the Series 390, which has a bottom fitting depth of 1-1/8". That's not something we can tell from a photo, you just have to measure it as carefully as you can and use your best judgement.
