What Is A Central Tension System?
Katchakid CEO Blair Esson invented and patented the first central tension system close to 30 years ago as a means to get a pool safety net to the required tension without excessive physical exertion. Like tightening a drawstring bag the concept is to pull up and tighten a pool net from the center point of the pool through a series pulleys.
The Katchakid pool safety net has a built in centrally tensioned system (CTS) that can be adjusted from tight to very tight and is designed in such a way that most children under the age of 12 years cannot remove it. The series of pulley’s are set in a circular fashion, which open and close. The correct configuration and size of the CTS together with a necessary amount of pulleys determine a pool nets efficiency. The Katchakid uses an average of 12 to 16 pulleys per CTS.
Swimming pools with well-defined midpoints usually require one CTS whereas pools of unusual shapes such as L’s, figure 8’s, Lap-pools etc… will require more.
