## Abstract

The invention addressed in this application is non-injurious restraint type form of fencing designed to be used a perimeter or security fence. The fence is constructed of hollow polymer tubes arranged in horizontal rows affixed to a vertical post. The hollow tubular horizontal fence rails contain fibers that are coated with a moisture cured adhesives and the fibers are secured at one end to the end cap of the tubes. The tubes are sealed and slightly pressurized with a dry inert gas, so that upon breakage of the tubes by a person attempting to scale the fence, the fibers are expelled out of the tubes and entangle the would be climber. The tubes are constructed of a brittle material, like polystyrene, or material which will become brittle upon treatment with ultra violet (UV) radiation or heat.

## Claims

### Claim 1

A fencing system comprised of hollow polymer tubes arranged in horizontal rows affixed to vertical fence posts, the hollow polymer tubes contain fibers which are coated with a moisture cured adhesive where said fibers are secured at end to an end cap of the tubes, where said tubes are constructed of a brittle material or a material which will become brittle upon treatment with ultra violet radiation or heat and said tubes containing the adhesive coated fibers are sealed and pressurized with a dry inert gas, such that said adhesive coated fibers are expelled out of the tube upon breakage of said tube.

### Claim 2 (depends on 1)

The fencing system as recited in claim 1, wherein said hollow polymer tubes are constructed of polystyrene.

### Claim 3 (depends on 1)

The fencing system as recited in claim 1, wherein said hollow polymer tubes are constructed of a polymer which becomes brittle upon treatment with ultra violet radiation or heat.

### Claim 4 (depends on 1)

The fencing system as recited in claim 1, wherein said hollow polymer tube is three to twenty feet in length and one-half to two inches in diameter.

### Claim 5 (depends on 1)

The fencing system as recited in claim 1, where said adhesive coated fibers are made from nylon, cotton, sisal, hemp or jute.
