Corner assemblies for protective barriers for protecting assets (e.g., electrical power transformers and other substation components). The corner assembly includes two guide structures oriented perpendicular to each other. The corner assembly includes at least two protective member assemblies disposed within the two guide structures. Each protective member assembly includes two side members within protective members extending horizontally between the two side members.

A tensioned barrier, comprising a chain link or mesh fence providing a secure perimeter, is provided. The fence is tensioned by grabbing and holding one end of the mesh link, wrapping the mesh around a perimeter of the fence poles, including wrapping the mesh around the outside of corner poles, pulling the mesh at its distal end to create a tension in the mesh and then grabbing the distal end of the mesh and securing it to the final fence pole. The fence is created using a high strength small weave mesh that resists cutting and climbing. In one embodiment the fence is created adjacent a structure, using the structure as an element of the barrier. In another embodiment, a fully fenced area is created by placing the first fence pole at a small distance apart from the final fence pole, with the other poles forming a perimeter, and tensioning and wrapping the mesh around all of the poles, affixing the ends of the mesh to the first and final poles and providing a gate or door between the first and final poles.

A barrier comprising deterrent material including an elongate core wire, and an elongate strip which encloses a part of the core wire, a first elongate portion of the strip which projects as a first elongate flange and a second elongate portion of the strip projects as a second flange, wherein the first flange is formed with a first set of first corrugated formations comprising alternating first channels and first ribs which extend laterally relative to the core and the second flange is formed with a second set of second corrugated formations comprising alternating second channels and second ribs which extend laterally relative to the core, the deterrent material being formed into a plurality of helical coils which extend around a central elongate axis and wherein the first and second flanges extend transversely relative to the elongate central axis.

Provided is a fence which can prevent a person from clambering over the fence while ensuring sufficient ventilation. The fence includes: a plurality of posts; a pair of plate members extending in a horizontal direction and spaced away from each other in a vertical direction; and a blocking member arranged in the space between the plate members for keeping a foot of a person from entering the space between the plate members to prevent the person from clambering over the fence, wherein a lower end of the blocking member is spaced upward from the plate member at a lower position, and defines a lower gap against an upper surface of the plate member at the lower position, the lower gap having such a dimension as to keep a tip of the foot of the person from entering the lower gap.

A barrier assembly including a bracket member (10) with a base (14) and an inclined upper part (16). An alignment adaptor (36) may be provided which mounts the bracket (10) at an inclination to a mounting surface for instance for use in corners. The bracket member 10 may be mounted on an extension member (68) which enables the bracket member to extend higher than would otherwise be the case.

An exemplary bollard fence includes bollards having bottom ends secured in a concrete base, the bollards spaced apart and extending axially from the concrete base; an elongated member moveably disposed inside of each of the bollards, and a header member laterally interconnecting the upper ends of the bollards.

A razor wire barrier is disclosed. In some embodiments, the razor wire barrier includes a frame including a floor and a plurality of walls defining an interior area. The razor wire barrier may further include a first section of razor wire within the interior area, and a component receptacle extending along the floor, adjacent the first section of razor wire. The component receptacle is operable to receive a component of a machine for moving the frame. In some embodiments, the component receptacle is a hollow member operable to receive a forklift prong. In some embodiments, the razor wire barrier may further include a second section of razor extending along the plurality of walls. In some embodiments, the first section of razor wire includes one or more coils of concertina razor wire, and the second section of razor wire includes one or more panels of razor wire.

A bollard wall system for efficiently assembling a bollard wall. The bollard wall system generally includes a support structure having a plurality of sleeves adapted to be positioned within a trench filled with concrete, and a plurality of bollards positioned within the plurality of sleeves in a vertical manner. Each of the plurality of bollards are lifted and lowered into a corresponding one of the plurality of sleeves by a crane vehicle to form a bollard wall.

An animal repelling device may include a first mounting bracket and a second mounting bracket, each of which includes an upper section and a lower section. The upper section may include a vertical tab, a notch formed in the vertical tab, and ribs coupled to opposing sides of the vertical tab. The lower section may include a foot coupled to a sidewall, the sidewall comprising a curved inner surface configured to mateably couple with a fence. A roller may be disposed between, be rotatably coupled to, and extend axially between, the first mounting bracket and the second mounting bracket, the roller comprising an aligner that biases the roller back to an initial at rest position. An attachment clip may be releasably coupled to the notch of the vertical tab.

Safety rail assemblies comprise horizontal beveled rails having a beveled face, a width, a height, a bottom, a back, and a bevel angle. The safety rail assemblies are configured to selectively attach to horizontal rails and pickets of one or more fence segments. The bottom of the safety rail assemblies attaches to a top of the horizontal rails. The back of the horizontal beveled rails attaches to the pickets. The bottom is a horizontal plane. The back is a vertical plane. The beveled face comprises the bevel angle and represents a face of the horizontal beveled rails being non-horizontal and non-vertical between the back and the bottom.
