Caldwell window balance
Caldwell
They are 1/2 inch wide
30 inches long (metal part)
Thanks for posting. See either our S380-30 or S385-30. The only difference between these two Series is the 'depth' of the bottom nylon shoe. With the Series 380 the depth of this nylon shoe is 1", whereas with the Series 385 it is 1-3/32". Compare with your own and see what is best.
Once you know which balance to select, you must choose a stamp option. Your stamped number of 29 3 conforms to our stamp option of 2930. Let us know if you have any questions.
It's hard to tell from this photograph, but unless the balance shoe looks like its deeper than 1" at any point, then I think the Series 380 is the right option.
My pleasure. Let us know if you have any questions.
