Net Fence
The Net Fence™ is an attractive security device for protecting
large, open areas by snaring and immobilizing vehicles. This snaring
effect is accomplished in a manner similar to that used on aircraft
carriers for halting incoming planes.The Net Fence's™ incredible
vehicle-stopping capability is achieved by the use of specially designed
high strength lateral members (rails) in conjunction with uniquely
constructed posts, anchorages, and cables. The system was designed
to stop a 15,000 lb. vehicle traveling at 50 mph (DOS K12 crash rating).
The result is a physical perimeter security system that appears to
be a typical post and rail fence but that is truly an effective vehicle
barrier.
The Net Fence™ was designed for facilities where extensive perimeters
must be secured from vehicle intrusion. Additionally, for situations
where concrete vehicle barriers might be a consideration, the Net
Fence™ can provide equal or superior security in an attractive
fashion and without obstructing the line of sight. Crisp's Net Fence™
provides the same vehicle stopping security to the rest of your perimeter
that our barriers and gates provide for your roadways.The Net FenceTM
is of particular interest to military bases, nuclear power plants,
and defense industries.
Net Fence™ technology can be applied to a wide range of fence
styles and perimeter situations. The fence can be customized to blend
with virtually any existing perimeter environment, and the number
of rails can vary. Chain link fences were designed to stop people
and animals, not vehicles! The Net Fence™ with chain link fences
provides a complete counter intrusion system.
The steel posts are a nominal 7 feet long and set in place with concrete.
Nominal post to post spacing is 10 feet - 20 feet. Installation requires
boring into the subsurface to nominal depths of 5 feet. The buttresses
or superposts are placed at corners and 200 feet intervals along the
perimeter to give added strength and elasticity to the cable. They
can also be placed in rolling terrain where the slope is greater than
a 3 feet rise or fall in 100 feet. After placement the superposts
will be filled with concrete.
Because the Net Fence™ is constructed of high strength materials
and is galvanized, epoxy painted or powder coated it is maintenance
free.
