window balance broken string.

Thanks for posting. Can you confirm both of these channel balances have the same nylon attachments? And can you confirm the length of the metal channel on each balance, not including those nylon attachments, is 27"? If so, see either our S380-27 or S385-27. 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 select a stamp option. Your stamp code of 26-4 conforms to our stamp option of 2640, for a window sash in the weight range of 19 through 26 lbs. Let us know if you have any questions.
