chanel window holder

Thanks for posting. Double-check the length of the metal channel. Do not include the nylon attachments at both ends in this measurement. I suspect it will be 27" long. If so this is probably either an S380-27 or S385-27 Channel Balance. The only difference between these two balances is the 'depth' of the bottom nylon shoe. See below. Measure your old balance's shoe depth to see what matches best. For a stamp option choose 2640.

Comparison of the S378, S380 and S385 balance shoes.
