A chain link fence terminal post is a critical structural component in a chain link fencing system, serving as an anchor point that provides stability and support for the entire fence line. Unlike standard line posts that primarily support the fence fabric along straight runs, terminal posts include posts where the fence ends, where it turns, and where there are gates.
Understanding Terminal Posts
Terminal posts are strategically placed throughout a chain link fence layout to handle the tension of the fence fabric and provide robust support at key points. They are typically larger in diameter and heavier gauge than the intermediate line posts to withstand the forces exerted on them.
Key Locations and Functions:
- End Posts: These posts mark the beginning and end points of a fence run. They are essential for anchoring the tensioned chain link fabric.
- Corner Posts: Installed where the fence line changes direction, corner posts bear the tension from two different fence sections, requiring significant strength and stability.
- Gate Posts: These are specialized terminal posts that support gates, enabling them to swing open and close smoothly. As highlighted in the reference, gate posts often include hinges on one side for the gate to attach to and a latch on the other to keep the gate closed.
Role and Importance in Fence Structure
Terminal posts are the backbone of a chain link fence, ensuring its longevity and structural integrity. Their primary roles include:
- Anchoring: They serve as the main anchor points for the entire fence system, resisting the pull of the tensioned chain link fabric.
- Support: They provide rigid support for the top rail, bottom tension wire, and fence fabric, preventing sagging and maintaining a taut appearance.
- Gate Operation: For gate posts, they facilitate the smooth operation of gates, bearing the weight of the gate and supporting the hinges and latch mechanisms.
Distinguishing Terminal Posts from Line Posts
It's important to differentiate terminal posts from line posts, as they serve distinct purposes and have different specifications:
| Feature | Terminal Post | Line Post |
|---|---|---|
| Primary Role | Anchoring, support at ends, corners, and gates | Supporting fence fabric along straight runs |
| Size/Strength | Larger diameter, heavier gauge, more robust | Smaller diameter, lighter gauge |
| Fittings | Equipped with tension bands, brace bands, rail ends | Typically uses tie wires or hog rings |
| Location | Ends, corners, gate openings | Between terminal posts on straight sections |
| Tension Load | Bears significant tension from fabric | Bears minimal tension directly from fabric |
Components and Installation Insights
Terminal posts require specific fittings to properly secure the chain link fabric and other fence components. These include:
- Tension Bands: Used to attach the chain link fabric to the post, allowing for proper tensioning.
- Brace Bands: Secure various fittings, such as rail end cups or gate hinges, to the post.
- Rail End Cups/Bullet Caps: Connect the top rail to the terminal post, providing a stable frame for the fence.
- Post Caps: Protect the top of the post from weather elements.
- Tension Bar: A vertical bar woven through the end of the chain link fabric and secured to the post with tension bands.
Proper installation of terminal posts involves setting them in concrete to ensure maximum stability and a secure foundation, especially given the tension they need to withstand.
Terminal posts are indispensable for the stability, functionality, and durability of any chain link fence, forming the strong framework upon which the entire system relies.
