  • To measure the balance, measure the metal channel only. The stamp is located on the balance and is either pressed into the metal or printed on it. If the balance is not available, measure the height of the visible glass. This will be your length. Then remove and weigh your window sash on a bathroom scale and select your appropriate weight range. These measurements are crucial to the performance of the balance.
  • The information is based on two balances per sash with no weatherstrip friction considered.
  • AAMA Class 2 Verified Component
