Balance Help

Thanks for posting. If the metal channel, not including the nylon attachments, is 30", then 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 stamp code of 29 9 is from an older rating system we no longer use. Weigh your window sash. You can match that precise weight with one of the weight ranges listed for each stamp option on the product page.
