barbed tape

Barbed tape is very similar, but has no central reinforcement wire.

Barbed tape is also characterized by the shape of the barbs.

More recently barbed tape has been used in more commercial and residential security applications.

The term "razor wire", through long usage, has generally been used to describe barbed tape products.

From the early 1970s, unreinforced barbed tape was commonly used in perimeter barriers of US prisons.

Due to its dangerous nature, razor wire/barbed tape and similar fencing/barrier materials is prohibited in some locales.

Each unit serves a specific segment of the prison population, and each unit is surrounded by walls with barbed tape.

In the early 1980s, several manufacturers began offering barbed tape with an embedded reinforcing wire and the product has been the subject to a patent dispute.

Barbed tape (razor wire)

This type of barbed tape provides a good physical deterrent as well as giving an immediate alarm if the tape is cut or severely distorted.

Barbed tape or razor wire is a mesh of metal strips with sharp edges whose purpose is to prevent passage by humans.

Early brand names of reinforced barbed tape included "Man Barrier" and "Razor Ribbon".

Like barbed wire, barbed tape is available as either straight wire or spiral concertina wire.

Barbed tape was first manufactured by Germany during World War I, as an expedient measure during a shortage of wire.

Apparently, all twenty-two victims of the 1951 massacre were dumped into the river on Enver Hoxha's orders, only to later be found wrapped tightly in barbed tape.

In the military science of fortification, wire obstacles are defensive obstacles made from barbed wire, barbed tape or concertina wire.

Typically the core wire is galvanized and the tape is stainless, although fully stainless barbed tape is used for expensive permanent installations or under water.

Residential usage of barbed tape has been criticized by some as the aggressive appearance of the barbs is thought to detract from the appearance of a neighborhood.

Starting in the late 1960s, barbed tape was typically found in prisons and secure mental hospitals, where the increased breaching time for a poorly equipped potential escapee was a definite advantage.

Unlike barbed wire, which usually is available only as plain steel or galvanized, barbed tape is also manufactured in stainless steel, to prevent the points from rusting to bluntness.

Unable to control B13 the authorities construct a high wall topped by barbed tape around the entire area forcing the inhabitants within to survive without education, proper utilities or police protection behind the containment wall.

Until the development of reinforced barbed tape in the early 1980s, it was rarely used for military purposes or genuine high security facilities because, with the correct tools, it was easier to breach than barbed wire.

This early barbed tape had triangular barbs and no reinforcing wire; consequently, it was more difficult to cut with ordinary wire cutters, easier to cut with shears, and was generally of lower tensile strength.

In many high-security applications, barbed tape supplanted barbed wire, which could be circumvented relatively quickly by humans with tools, while penetrating razor wire barriers without tools is very slow and difficult, giving security forces more time to respond.

As the Hudson River spills past 59th Street and down to the Battery, it is separated from the city by a series of industrial complexes devoted to garbage and electrical power, surrounded by fences festooned with barbed tape and no-trespassing signs.
