Introduction
The combination of stainless steel spiral rod torsion and of tension springs, produces a self-contained balancing device capable of maintaining the equilibrium of a sash window at any point in the travel of the sash.

Application
A pair of balances is required for each sash. The balances are housed in a groove in either the outer frame Jamb, or alternatively in the sliding sash stile.

These grooves should be true and completely smooth. The top part of the balance is screwed into the Jamb and the sash attachment at the lower end, is screwed to the bottom rail of the sash. Where the upper sashes have horns, a channel type fitting is screwed to the side of the horn and subsequently the balance attachment is slotted into the channel.

All balances have semi-flexible tubes which enable the balance to be slightly bowed during installation. This can be vital in a replacement situation and is a feature unparalleled by any other balance manufacturer.
