This standard has been approved for use by agencies of the Department of Defense.
aluminized—in chain link fabric, describes fabric woven from steel wire that is coated with aluminum before weaving (see
Specification A 491 ).
barb—as related to barbed wire- a short length of wire, with exposed ends cut on a bias to produce sharp points. See Specifications
F 1665 and A 121.
barbed tape—strip of metal, machined to produce clusters of sharp points (see Terminology F 1379 for further information).
barbed wire—a fabricated wire product consisting of two line wires twisted to form a two-wire strand, into which 2–point or
4–point barbs are tightly wrapped and locked into place at specific intervals. (Syn. barbwire). See Specifications F 1665 and
A 121.
barbed wire arm—a post fitting used to hold barbed wire in place. May be vertical or angled to hold three or more strands of
barbed wire, or “V” shaped to hold six or more strands of barbed wire.
barbed wire arm base—a casting of aluminum, malleable iron, or steel, used in combination with one or two barbed wire
extension arms held in place by a bolt and nut.
barbed wire extension arm—pressed aluminum or pressed galvanized steel used in combination with barbed wire arm base to
hold three strands of barbed wire either vertically or angled in or out from the fence line. Also used in pairs in a “V”
configuration to hold 6 strands of barbed wire.
bottom protective plate—a safety device installed on a Type II, Class 1, cantilever slide gate with external rollers to isolate the
lower roller mechanism to reduce the possibility of contact with the roller mechanism by a person. See Specification F 1184 .
bottom rail—horizontal member of the framework running continuously along the bottom edge of the fence.
boulevard clamp—a two piece clamp with carriage bolts and nuts designed for 180° horizontal rail connections to a line post (also
called line rail clamp).
brace band—a symmetrically formed strip of metal shaped to fit around a post and used with a carriage bolt and nut to attach
the rail end or brace rail end truss rod tightener to the post (see Fig. 1). Also used for attaching barbed wire, tension wire, and
other items to a terminal post.
brace rail—a compression member at terminal posts or corner posts.
brace rail end—a cup-shaped fitting similar to a rail end with provision for attaching a truss rod.
cantilever slide gate—any horizontal slide gate spanning an opening lacking a top or bottom support within that opening (see
Specification F 1184 ).
center stop—a device to receive and hold the drop bar on a double gate.
corner barbed wire arm—a combination post cap and fitting used to hold barbed wire in place on a corner post. May be angled
in or out from the fence line to hold three or more strands of barbed wire, or “V” shaped to hold six or more strands of barbed
wire.
corner post—a terminal post, at which the direction of the line of fence changes in two or more directions (see Fig. 2).
corner rail clamp—a two-piece clamp with carriage bolts and nuts designed for horizontal rail connections to a 90° corner post.
diamond—the opening formed by the woven wires in chain link fence fabric.
diamond count—the number of diamond openings from one edge of fabric to the other. The count of a given fabric shall begin
at the first completed diamond at one edge and continue to the unfinished (half) or full opening at the other edge (see Fig. 3).
double drive gate—a gate comprised of two gate leaves which is used to close a gate opening through which vehicles are intended
to pass. While often referring to a swing gate (that is, double swing gate), the gate may be any double leaf gate intended for
This terminology is under the jurisdiction of ASTM Committee F14 on Fences and is the direct responsibility of Subcommittee F14.40 on Chain Link Fence and Wire
Accessories.

fabric (chain link fence)—a fencing material made from wire helically wound and interwoven in such a manner as to provide
a continuous mesh without knots or ties except in the form of knuckling or of twisting the ends of the wires to form the selvages
of the fabric (see Fig. 5).
