30" WINDOW SPRING REPLACEMENT
Thanks for posting. This entirely depends on the style of the attachments at either end of your balance. Could you show us photos of these? We should be able to make a determination based of those attachments. Thanks.
Thanks for the extra photos. Can you confirm that the metal channel, not including the end attachments is 30"? If so, 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.
You must select a stamp option. Your stamp of 29 5 conforms to our stamp option of 2950, for a window sash weight range of 28 through 32 lbs. Let us know if you have any questions.
