<p>Embodiments of this invention include describe an improved apparatus and method for using ropes with security units/barriers deployed in water or on land. The ropes are preferrably deployed with hollow plastic tubes which protect the ropes from abrasion, UV light, and damage from animals. A rope contained within a tube is under no stress until an intruding object impacts the security barrier and the security barrier reaches its elastic limit.</p> |
