This is the problem that LQ Housing had to deal with in South London recently before they called in Vandgard Anti Climb Guards.
Free running is fine, but breaking into private property is definitely not. The entrance gates in the picture are now protected with Vandgard and the problem solved, neatly and without intent to cause harm.
Vandgard’s rotating action creates an unstable anti climb barrier which rolls if anyone attempts to climb over it. Visually it is a clear warning in itself and so does not contravene either the Health or Safety at Work Act, COSHH regulations or any other civil or criminal laws.Because it is lightweight, weighing only 4 kilos per metre, it is also very easy to handle and can be used on even wooden or mesh fencing. Due to its ease and speed of installation, it also offers substantial cost benefits over traditional methods of protection, such as coils of barbed wire.
