Need two sets of channel balances for Viking windows

A home owner from Oakland CA says:
Hi,

I'm hoping you can help me get two sets of channel balances:
1) Length 21 inches, no stamp but according to weight would be 2010
2) Length 18 inches, no stamp but according to weight would be 2010

Both have the same top and bottom parts--please see photos above.

Thanks for your support. Cheryl

Thanks for posting. Please confirm that you are not including the end attachments in your measurements. If so, see our S395-21 and S395-18. Please note that the stamp options differ depending on the balance length--there is no 2010 option for a S395-18. In lieu of any stamps, it sounds like you have wisely gone to the trouble of measuring the weight for each window sash; just match those measurements with the correct weight range listed alongside each stamp option on the balance product pages.
