Being extremely versatile, the CACTI® complements our own manufactured fence and gate range but is also suitable for the traditional palisade and welded mesh fences, which we also supply and install.  The CACTI® can be fitted at almost any angle on walls, rooflines, drainpipes and numerous other applications.

The CACTI® is a robust, powerful device that is a very tenacious deterrent if challenged, yet aesthetically pleasing, blending perfectly into its environment.

Unlike conventional alternatives, the CACTI® will not rust, twist or bend nor does it contain any entrapments or impaling features yet will deliver an element of discomfort to potential intruders.
