Composite fence terms, explained.

Use this glossary while comparing products, drawing a layout, or reviewing a material list. Project documents and local requirements govern when they are more specific.

A–Z reference

Know what belongs in the system.

Aluminum fence post
The structural post used between standard panel bays. Compoxen standard fence posts and heavy-duty gate posts are separate products with different dimensions and uses.
Bracket kit
The hardware used to connect the rail system to a post. Confirm the required quantity and compatibility for the selected panel and installation method.
Closing post
An additional post used to finish an open end of a fence layout when the included posts do not close the final section.
Co-extruded shell
An outer layer formed with the composite board during manufacturing. It provides the visible color and textured surface and helps protect the core from routine exposure.
Composite fence board or slat
An individual fence board made from a composite material. Boards are assembled with the compatible rails, posts, brackets, and caps to create a panel bay.
Double gate
A two-leaf gate that meets in the center to create a wider opening. The opening, posts, hinges, latches, drop rods, clearances, and support all need to be planned together.
Finish
The board color and surface appearance. Compoxen offers Harbor Slate, Mesa Taupe, Shadow Forge, Redwood Ember, and Cocoa Ridge.
Full privacy
A board layout designed to block direct sight through the main panel field. Small installation clearances may still be required around posts, grade, and gates.
Full-trellis
A horizontal board layout with repeated open spacing from top to bottom. This is not offered as a vertical Compoxen panel style.
Gate post
A heavier post intended to support a gate assembly. Do not substitute a standard panel post without an approved system design.
In-ground installation
A method in which extended posts are placed in prepared footings. Depth, diameter, concrete, drainage, frost conditions, and engineering depend on the site and local requirements.
Linear foot
A one-foot length measured along a fence run. Linear footage describes length, not the number of panels, posts, corners, or gates.
Material takeoff
A list of product quantities derived from a drawing or field measurements, including panels, posts, rails, brackets, caps, gates, and accessories.
Mid-trellis
A horizontal layout with a solid lower section and open spacing above. It balances lower privacy with a lighter upper portion.
Panel bay
The section of fence between two post locations. A nominal panel size and the actual installed spacing may differ, so use the current system documents.
Surface-mount installation
A method that uses a mounting bracket to secure the post on a flat, structurally suitable hard surface. The surface, anchors, edge distances, loads, and local requirements must be reviewed for the project.
Top and bottom rails
The horizontal aluminum components that support and finish the composite boards in a panel assembly.
