The principle
behind the PivotTrue Interlocking Balance System is that window hardware
should perform as a group of elements that interact and function
together.
PivotTrue
successfully achieves this by uniquely adapting the patented pivot
mechanism with the window balance to form a system that not only
functions as an integral part of the window, but together, creates
a structural union between your sash and frame. A drop-in pivot bar
design and substantially higher structural-load performance makes
PivotTrue a "true" innovation for coils, spirals and block & tackle
balances.
