Replace Harcar window balance rods

Question

Harcar single hung non-tilt windows

Channel balance rods.

Only marking is 2830.

Channel length is 29" measuring only metal.

30" with plastic clips.

Channel width 9/16" so I believe that is 1/2" in trade.

Thanks for writing in! Your channel balance is either the S380-29 with a 1" shoe or the S385-29 with a 1-3/32" shoe. To determine which series is needed for your window, look over the dimensions from the diagram below to confirm the depth of your bottom shoe.

Let me know if it does not match either measurement. You'll need to select the 2830 stamp for a 16 to 23lb window.
