96BU Series Constant Force Balance

96BU Series Constant Force Balance

The 96BU Series Constant Force Balance is a durable stainless steel coil spring to support the sash and provide smooth, controlled operation in tilt-in windows. Each coil is specifically calibrated to the weight of the window sash, helping balance the sash as it moves up and down. When properly matched and installed, the balance helps the sash stay in position when opened and remain securely closed when lowered. 

• Works with multiple brands of coil system that fit the specifications
• Available in 3.5 lbs, 4.5 lbs, 5.5 lbs, 6.5 lbs, 7.5 lbs, 9 lbs, and 10 lbs weight ratings
  
• To find the correct replacement, check your old coil spring for a stamp or imprint weight rating. This indicates the balance weight needed for your window.
  
• Each coil balance is rated to support a specific amount of weight. When multiple coils are used together, their weight ratings combine to support the full weight of the window sash.
• The coil measures 1/2" thick and fits in a 1-1/4" pocket.
• Used with a compatible pivot shoe (sold separately)
• Designed for left or right side installation.
• Works with 160 series coil balances

Best Practice

• For best performance, window balances should be replaced in pairs (sold individually). Installing one new balance alongside an old one can lead to uneven operation and premature wear. Replacing both ensures smooth, long-lasting performance.
• If the balancer you need is not listed or you are unsure which option to choose, contact our experts for assistance.
