Stable Support for Exterior Gate Installations

This in-ground gate post is designed to create a strong, stable foundation for composite and aluminum gate systems. With a nominal width of 4 inches, an actual width of 3.9 inches, and a height of 8 ft, its heavy-duty construction accommodates the additional demands associated with swinging gates.

Aluminum Alloy Construction

Manufactured from 6063-T5 aluminum alloy, the post is made for long-term exterior use. It is designed to resist rust, corrosion, moisture, UV exposure, high humidity, rain, and changing outdoor weather conditions while maintaining a clean appearance alongside composite or aluminum fencing.

For Single and Double Gate Layouts

The post can be incorporated into both single- and double-gate configurations. It is suitable for pedestrian gates, driveway gates, backyard entrances, garden entrances, side-yard access points, residential property entrances, privacy fence gates, multifamily properties, and commercial entrances.

In-Ground Installation

Designed for direct placement into the ground, this post is especially appropriate for installations over soil or dirt where a securely embedded support is needed. Its 8 ft length allows part of the post to be set below ground while supporting the above-ground gate system. Appropriate installation depth and site preparation should be determined for the specific gate layout and ground conditions.
