28 3 jk Caldwell

Quick Learner from Seattle, wa
I am looking to replace a jk Caldwell channel balance 28-3. It is 29 in long and 1/2 in wide. Appears I need a series 385, but I am not positive. I also don't know what sash weight I have. Recommendations?

Thanks,

John

Hey, John, thanks for posting. What is the depth of the bottom shoe? The Series 385's bottom bottom shoe is our 15-004, which has a depth of 1-3/32". How does that compare to yours?

Usually a stamp of 28 3 corresponds to our 2830 option, but I recommend that you remove your sash from the window and place it on a scale to make sure it fits under the 2830's suggested weight range just in case.

Thanks for the help. Sash is 13 lbs, so will go with the next option down.
