As the market demands bigger and heavier windows, traditional balances struggle to support their weight with easy operation. Amesbury Group has developed SuperBoost balances to meet the needs of heavier sash weights. The F series is able to carry sash weights up to 80 pounds and the K series can support sash weights up to 120 pounds, the company reports. The balances are shipped pre-tensioned and can be field adjusted after installation without removal.
