SKU:
Shipping calculated at checkout.

The 31 Series is a standard coil spring window balance. This balance is designed for residential window applications. These balances feature a 9/16" (0.562") channel depth and single, tandem, or triple case applications. This balance system is designed to reduce operating force and operate with reduced noise over other balance systems. These balance weights are evenly divided. For example, if your sash weighs 14lbs, you would need one 7lb balance on each side of your sash. 

To Select the Correct Coil Spring Balance

  • First, determine the weight of the balances you need by weighing the sash or looking at the stamp on the balance. The stamp will be a number printed onto the plastic housing. This number will be your balance weight. 
  • Next, you will need to select the appropriate locking collar color. This locking collar is the rotating plastic cam that your pivot bar slides into.
  • Finally, you will choose whether or not you need additional coils for tandem (one additional coil) or triple case (two additional coils) applications.
