Kinco channel guide replacement

Question

I am looking to replace some channel guides on what I think are Kinco windows.  I believe they would be your 380 model as I measured the shoe, and it has a 1" depth.  The stamp indicates 28 4, which I think translates to your 2840; however the sash actually weighs 16 lbs; so should it be 2830.  Please let me know.

Hello,

You are correct that the (28 4) stamp on your balance would normally indicate a 2840 spring strength option for your S380-29 balances. It is possible that someone replaced your window balances with what they had on hand at some point. If your window sash weighs 16 pounds, I agree that the 2830 would be a better option.

As for your top sash guide, start by comparing the dimensions of our 18-166 to yours and let us know how they compare. Thank you!
