Help Identify Channel Balance Part

Thanks for posting. Please confirm that the metal channel, not including the end attachments, is 30" long and 1/2" or 9/16" wide. If so, see 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 what balance to select, you'll need to choose a stamp option. Your stamp option of 29-9 is a little unusual, though. You will need to weigh your window sash. You can then match that exact weight with one of the weight ranges listed with each stamp option on the product page. Let us know if you have any questions. 

Do your best to measure the length of the shoe from front to back. We understand it is difficult with an part that is not completely flat, but this measurement will help determine which series balance you need, as well as the physical weight of your sash for the proper stamp option.

Comparison of the S378, S380 and S385 balance shoes.

The depth of the shoe does matter for proper balance replacement recommendations so we thank you for measuring that for us. Your replacement balance is going to be the S385-30 with the 2975 stamp option, again we thank you for weighing the sash and confirming this for us.

This balance should work for you, if there is anything else we can do for you, please let us know.

You definitely chose the right stamp, but I can't tell you if the Series 385 is right. There's only one way to know if you picked the right Series and that's by comparing the nylon fittings on your balance to those we show on the Series 385 store page.
