There are a lot of options for security fences that are very difficult or nearly impossible to climb over. However, in situations where the highest level of security is required, climbing is not the only issue which needs to be taken into consideration. Fences also need to be secured against a possible breach by a vehicle. This issue can be resolved by installing concrete walls or a heavy metal fence, but this is often a very expensive and unnecessary choice. Thankfully, anti-ram cables can effectively and economically protect your fence against possible vehicle breach.
