Balance Spiral Units – Adjustable Weight Ranges & Foot Configurations
The Whitco Balance Spiral Units are designed to deliver smooth, controlled movement for both aluminium and timber frame double-hung windows. These spiral balances support the reliable operation of top and bottom sashes, helping windows glide effortlessly while maintaining long-term performance. With adjustable tension and multiple weight capacities, this range is suitable for a wide variety of residential and commercial window applications.
Product Features & Construction
Manufactured with a narrow, fully sealed body, these spiral balances use an oil-tempered carbon steel torsion spring combined with a zinc-plated variable pitch spiral for consistent and adjustable performance. The steel zinc die-cast fixing plug and tough ABS polymer outer casing provide durability, while the corrosion-resistant stainless steel sash foot plate ensures dependable operation over time. Adjustable spring tension allows fine-tuning to suit different window weights, and optional shock-absorbing stops help reduce wear during operation. All units are supplied in a black finish and are available in trade pack format only. Adjustable foot configurations require a tension key for correct setup. Proudly made in Australia.
Applications
Ideal for double-hung window systems, these balance spiral units are suitable for aluminium and timber frames where smooth sash movement, controlled balance, and long-term reliability are required. They are commonly used in residential housing, renovations, and commercial window installations.
Available Variants
Available across multiple unit sizes including 440, 460, 480, 500, 510, 520, 540, 560, 580, 600, 610 and 620, with adjustable weight ranges covering 2.25–7.25kg, 7.25–10kg and 10–14kg, supplied either with no foot or with a standard foot attached, all provided in trade pack configurations to suit different window sizes and load requirements.
