Wingless Window Balance

Thanks for writing in! Your window balance is similar to the S351-22 and S390-22 wingless balances. To determine the right series for your repair, you'll need to measure the depth of the shoe.

Our 2130 stamp will support a sash weighing 12 to 15lbs. You may want to double check that your sash weight falls between this range.
