Replacement channel balances and plastic parts.




Thanks for posting. Based on the nylon attachments this looks like either a Series 380 or Series 385 Channel Balance. The only difference between these two balances is the 'depth' of the bottom nylon shoe, as shown below. Measure your old balance's shoe to see what matches best.

For the balance length, measure the metal channel. Do not include the nylon attachments on both ends in that measurement. Finally, you have to choose a stamp option, which reflects the balance's strength. If the window sash weighs exactly 36 pounds, you can use that weight to choose the right stamp option by looking at the table under the product description of whatever balance you need.
Finally, the Top Sash Guide might be either the 18-009 or 18-166. See below. Let us know if you have further questions.
