Double sprung Ultralift balances
Featuring a larger, 17mm diameter design, Ultralift balances can be specified for use in both tilt-in and standard sash window designs.
Unlike Spirex, Spiralift and Alumatilt balances, Ultralift sash window balances are double sprung, offering increased efficiency and a smoother operation. Because of this double sprung design, they can offer the end user up to 75% increased mechanical advantage compared with standard operation. They can also be installed in systems heavier than single sprung alternatives, being able to support sashes up to 27kg in weight, so are suitable for specifying in more substantial window frames.
Key features and design specifications of ultralift balances:
- Supplied in 17mm diameter PVC-U tubes in white, brown, grey and cream colours
- Suitable for sashes weighing between 6kg – 27kg
- Double sprung to provide extra mechanical assistance
- Can be installed in both traditional sliding sashes and tilt-in configurations
