2630 window channel balance

Question

I removed 1 side of the window channel balance because it broke. The identifying number is 2630 on the back. I need the whole replacement part with the clip and plastic ends. Please help me. Thanks

Thanks for posting. This looks like an S390-27, or maybe the S351-27. The only difference between these two channel balances is the 'depth' of the bottom nylon shoe. See the diagram below. Measure your old balance's shoe depth to see what matches best. For the stamp option, choose 2630.
