replacement channel balance

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. I can't entirely make our the stamp in your picture--does it say 29 3? If so, that conforms to our stamp option of 2930, for a window sash in the weight range of 16 through 23 lbs. If you are uncertain this is correct, you can always weigh your window sash and match that precise weight with one of the weight ranges listed for each stamp option on the product page. Let us know if you have any questions.
