Fence Terminology

Barbed tape – A mesh of metal strips machines together to produce clusters of sharp points.

Barbed wire –Steel fencing wire that has been constructed with sharp edges that are arranged in intervals along the strand. Most often used in agricultural fencing. It is also used in commercial fencing along the top of chain link, usually three strands.

Bottom rail – Horizontal member of the framework that runs continuously along the bottom edge of the fence.

Brace band – A strip of metal used to attach chain link fence fabric to line posts and also terminal posts. Can also be used for attaching barbed wire, tension wire, and other items to a terminal post.

Cane Bolt – Component of a double gate latch assembly. (Sometimes called drop rod)

Cantilever slide gate – Any horizontal slide gate spanning an opening that lacks a top or bottom, excellent alternative when outward/inward swing space is limited.

Center stop – A device used to receive and hold the drop bar on a double gate.

Chain link – A fence made from thick steel wire interwoven together to make a diamond pattern, typically galvanized but can be vinyl covered.

Corner post – The terminal post at any corner of the fence.

Deer fence – A fence designed to prevent the passage of deer, usually around 8ft tall. The fence also needs to be very tight, so woven wire is generally used.

Diamond – The opening formed by the woven steel wires in chain link fence fabric.

Diamond count – The number of diamond openings from one edge of the fabric to the other on a chain link fence.

Double swing gate – A gate with two hinged leaves, most often used to gate driveways.

End post – A terminal post either at the beginning or end of the fence line.

Fabric – A unique fencing material made from vinyl wound and interwoven in such a manner as to provide a continuous mesh without knots or ties.

Fence line-A boundary line that is created by a fence.

Fence tie – A wire, band, clip or fastener that is used to attach one piece of fence to a support structure.

Framework – A basic structure that supports the installed fabric and gates.

Galvanized – Typical refers to steel fasteners that have been coated in zinc to prevent corrosion or rust.

Gate – A structure that acts as a moveable barrier allowing access through a fence.

Gate frame – The structural portion of the gate.

Gate opening – The clear opening between the gate posts.

Gate post – The post in which the gate is attached by hinges and latches.

Gauge – The measure of the wires thickness.

Height – The distance between the ground and the top of the fence. In chain link fence, the distance before stretching from the top edge of knuckle or twist to the bottom edge of the knuckle or twist of the fabric.

High-tensile wire – A type of fencing that is made up of strong wires running horizontally through insulators attaching to fence posts.

Hog ring – A open wire clip designed to secure chain link fabric to horizontal tension wire.

Intermediate rail – a horizontal support element in which the fence boards are attached usually found in middle of fence.

Knotted –A mesh produced by knotting together steel wires.

Knuckle – The interlocking adjacent pairs of wire ends and bending the wire back into a loop.

Lattice fencing: A structure of crossed wooden or metal strips usually formed into a diagonal pattern on a fence.

Line post – A post that is located between terminal posts to provide support for the fence.

Line post cap – A cap that is used to cover the top of the fence post, usually used for decorative purposes.

Loop cap – A cap installed on a line post that has a loop through which to pass the top rail or tension wire, used to secure top rail.

Mesh – A type of fencing which results from the connection of vertical and horizontal wires. Based on the connection method, the tighter the mesh weave, the more resistant the fence.

Middle rail – Horizontal member of the framework running continuously at any point between the top and bottom of the fence (sometimes called intermediate rail).

Offset hinge – A hinge that permits the gate to swing 180 degrees from the closed to the open position.

Ornamental fencing– A fence made up of steel, iron, or aluminum. Provides for traditional fencing needs with added aesthetic appeal.

Panel clamp – A clamp that can be used for clamping together two in-line chain link fence panels.

Post hinge – A fitting attached to the gate post that functions with the frame hinge receptor, permitting the gate to swing.

Post & rail – Any fence that is made from horizontal rails fastened to vertical posts.

Privacy fence – A fence that has close fitting vertical pickets blocking views into a yard or area.

PVC – Poly-vinyl chloride coating on fence materials.

Racking – Installation of fence sections allowing the fence to follow the grade.

Rail – A horizontal support element to which fence boards or pickets are attached.

Rail end – The posts that are at the each end or corner of a run of fencing.

Rail spacing – The distance that is between each rail on a fence.

Section – The run of fence between each post.

Selvage – The finish on woven chain link fabric joining pairs of pickets.

Semi-private – A fence that provides a balance of privacy and airflow, larger spacing between the pickets than your general privacy fence.

Sight board – The top board that runs between the posts on a fence constructed of posts and wire.

Single swing gate: Any hinged gate that is built with only one leaf.

Sleeve, top rail – A fitting used to join two pieces of top rail together end to end.

Split Rail – A post and rail fence that is made from rough hewn wood.

Stair stepping – A method used for installing a fence on a steep grade, with uniform sections installed at different heights to create a “stair-step” appearance.

Stretching – A process of putting tension at the end of the fabric to make it hang uniformly between terminal posts.

Swage – A formed end of a piece of top rail that will fit into and join another piece of top rail.

Tension band – In chain link fencing, tension bands are steel bands attaching the tension bar to the terminal post.

Tension bar – A bar intertwined in the end of a chain link fence allowing the fence to attach to the terminal post.

Tension wire – A wire that typically is used along the top of a chain link fence in place of a top rail or along the bottom of a chain link fence for additional security.
