|The range starts with the Spirex, Spiralift, Alumatilt and Alumatilt Heavy Duty 14mm diameter balances.
The Spirex and Spiralift balances are designed for non-tilting sashes and the Alumatilt and Alumatilt HD are designed for tilt-in sashes. These balances are all single sprung and are wound to the required tension once installed in the window. They are traditional and cost effective for a sash weight range from 1kg to 18kg.
A popular product is the Ultralift balance. This is a 17mm diameter balance which is pre-tensioned in the factory. This double-sprung product, which increases balance efficiency, is again suitable for nontilting, tilt-in sash applications and can accommodate sash weights from 4.5kg to 31kg.
The final balance product is the Torso balance. This is also a factory pretensioned product supplied in three differing diameters of 17mm, 19mm, & 25mm. It can accommodate sash weights from 2.5kg up to 65kg.
