I see you ordered our S390-15 with a 1420 option. We do have stronger options for heavier sashes, but keep in mind that it is possible to have a balance that is too strong. I recommend weighing your sash on a scale and referring to the chart we have on the S390-15 store page. That will let you confirm which option would be the best match.
If you do need a stronger balance, you can return the ones you purchased for a refund and then place a new order as normal. See our return policy for more information. |
