In need of a pair of replacement window balances and release clips

A home owner from Easton, WA says:
The length of the metal channel is 20 5/8", the width of the channel is 9/16", the depth of the channel is 5/8"

I also need two replacement 1/4" metal release clips

Thanks for posting! We can make this balance, though it will need to be custom made. I'm told by our phone representative that you would like 2 of these. With that in mind I will email you a custom form and quote for a pair of these balances.
