There is provided a structure for making fences, grates, guardrails, and other similar carpentry products including a plurality of stakes (10) which retain and support an upper crossbar (20) and a lower crossbar (21) by mobile connections (30, 31). Each of the stakes (10) includes an elongated central body (11) and portions of reduced length (12, 13) projecting above and below upper crossbar (20) and lower crossbar (21), respectively. The connection of an upper reduced length portion (12) and a lower reduced length portion (13) to central body (11) being formed by mobile screw connections (30, 31) of the threaded shank/threaded hole type locking each of the crossbars (20, 21) to a stake (10). The screwing action being facilitated by an appendage (40) projecting from and frangibly connected to the portions of reduced length (12, 13) adapted to break and be completely removed from the portions of reduced length when the maximum tightening torque is achieved.

Techniques are provided for a metal connector for connecting a strut to a fencing strainer post. The connector includes a first portion and a second portion. The first portion being elastically deformable and arranged to fit around a strainer post. The second portion arranged, when the first portion is deformed, to be inserted into a cavity in a strut and arranged to engage the strut by an at least partial reversal of the deformation.

A barrier, such as fence panel, is formed from a plurality of channel-shaped rails and plurality of upright members. Each upright member traverses the rail channels of the rails forming the barrier and is mechanically connected to the rail, such that the upright member is selectively tiltable with respect to the rail within an angular adjustment range. The mechanical connection between rail and upright member may be formed by a weld, such as a resistance weld, by a permanent adhesive, or with a fastener such as bolt or screw. A tab that extends from the rail web may be used to connect a rail to an upright member. The tab may depend from a bracket installed within the rail channel, or may be cut out and bent into the channel from the web. The tab is rotatable about an axis situated at or adjacent the web.

A bollard panel having adjacent bollards and a gap between the adjacent bollards, a brace having a panel connector, a first longitudinal section, and a second longitudinal section, and the brace supporting the bollard panel in a vertical position relative to a ground with the brace disposed in the gap with the first longitudinal section located on a first side of the bollard panel, the second longitudinal section located on a second side of the bollard panel, and the panel connector attached to the bollard panel.

Border walls and related systems and methods are disclosed. A border wall may include a plurality of bollard fence sections adapted for engagement with corresponding base members. Each fence section may include a plurality of bollards. Each base member may include a plurality of openings extending downwardly from a top surface of the base member partially into the base member. The openings in the top of a base member are adapted for engagement with individual corresponding bollards on a bollard fence section. At least one of the bollards is “matched” to a corresponding opening in the base member so that the “matched” bollard, when inserted into and engaged with its corresponding “matched” opening, may function to support and/or align the bollard fence section. The base members may also include connectors, and/or mating alignment notches and protrusions, to facilitate joining and/or leveling of the base members to form a stable wall.

A modular privacy fence, which includes an upper rail, comprises a plurality of fence picket dividers on opposed outer side surfaces of the upper rail. The modular privacy fence also includes a fastener attached to the end of the upper rail, wherein the fastener is arranged to secure the upper rail to a fence post, and a bottom rail with a trough configured to receive a bottom portion of fence pickets. In some embodiments, the upper rail is configured to receive fence pickets between adjacent dividers. In such arrangements, the first plurality of fence picket dividers on a first side of the upper rail is offset from the second plurality of fence picket dividers on the opposing side of the upper rail in a direction parallel to the upper rail.

A knockdown fence assembly and methods thereof are provided. The knockdown fence assembly comprises a first connector piece, a first plurality of horizontal connectors, a second plurality of horizontal connectors, and a plurality of connector fasteners. The first connector piece includes a vertical main connector body with first and second pluralities of horizontal connector support pieces extending from the vertical main body in opposite directions. The first plurality of horizontal connectors are coupled to the first plurality of horizontal connector support pieces and extend into the vertical main connector body. The second plurality of horizontal connectors also extend into the vertical main connector body and overlap with the first plurality of horizontal connectors to define overlapping end portions. Each connector fastener extends through the vertical main connector body and a pair of the overlapping end portions of the first and second pluralities of horizontal connectors.

Fence assemblies are assembled from T-posts and crossmembers which may comprise rails formed from C-channels. The T-posts and rails are formed from pultruded fiberglass and can be connected together using bolts and nuts or push rivets. Cross members comprising wires or pultruded, fiberglass tubes may also be used.

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.

A barrier panel is formed of a first rail member and a second rail member with at least one vertical support member mounted to and extending between the first rail member and second rail member. The first rail member includes first openings spaced apart along its length. The second rail member includes second openings spaced apart along its length. Vertical cables are mounted to and extend between the first rail member and second rail member. A first end of each vertical cable is secured within one of the first openings and a second end of each vertical cable is secured within an opposite one of the second openings. End members configured to adjust tension in the vertical cables are concealed by a pair of leg members of the second rail member.
