The 50 Series is a "pencil" spiral window balance for tilt window applications. This balance is designed for residential applications. These balances feature a 3/8" diameter tube and lengths ranging from 10" to 45" and weight capacities from 4lbs to 34lbs you're sure to find the spiral window balance to fit your needs.

To Select the Correct Tilt Spiral Window Balance:

  • First, measure the length of the metal tube. Measure the metal tube only, do not include the colored coupling or spiral rod. That is your balance length. Check out our guide on measuring spiral window balances for more info on how to measure your balances properly.
  • Next, take a look at the color of the coupling on the tip of your balance. The color of the coupling indicates the weight capacity of the balance. Select the matching coupling color in the second dropdown menu. If you do not have a coupling or cannot determine the color, you will need to remove your sash and weigh it using a bathroom scale.
  • These measurements are crucial to the performance of the balance. If your balance does not measure an exact length, or if you have an attachment on your spiral rod, contact us before you place your order.
  • Does not include pivot locking shoes.
