Caldwell Series 250 Aluma-Tilt Heavy Duty 5/8" Spiral Window Balance for Tilt Windows

To Select the Correct Non-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. Longer Lengths Available, for Balances over 50" Call for Information or to Place an Order.
• Next, take a look at the color of the coupling on the tip of your balance. For the 250 series, the coupling color will be black. If you don't see a coupling or are unsure of your sash weight, remove the sash from your window and confirm the weight is between 30lbs and 40lbs.
• 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.
