Product Description
This 2.75″ 2-Way Aluminum Post is the straight line workhorse for modern aluminum and composite fencing. At a true 2.75″ square with integrated two-direction channels, it accepts panels on opposite sides to build long, perfectly aligned fence runs. The extrusion is architectural-grade aluminum for strength without excess weight, and the black powder-coat finish delivers a clean, uniform look that resists UV fade, moisture, and corrosion. At 8 feet long, it gives you ample set depth for concrete footings while maintaining the required above-grade height on typical residential and light-commercial installations. If your current line leans or flexes under wind load, upgrading to a properly sized 2.75″ line post with real channels solves the problem and keeps the top rail dead straight.
Applications
The 2.75″ 2-Way Aluminum Post is built for straight runs of fencing where panels align in parallel. Homeowners use it for property boundaries and privacy fences where consistent spacing and a strong line are critical. Contractors rely on it for larger commercial projects where hundreds of posts must perform under wind load while keeping the top rail perfectly level. Around pools and patios, this post offers the advantage of corrosion resistance, meaning water and chemicals will not compromise its integrity. In coastal areas, the aluminum and powder-coat combination stands up to salt spray and humidity, outperforming painted steel every time. If your project requires long, uninterrupted fence lines with a professional finish, this is the post designed for the job.
Installation
Installing the 2.75″ 2-Way Aluminum Post is straightforward yet delivers long-term strength if done correctly. Each post should be set into a properly sized concrete footing, deep enough to reach below the frost line in cold climates or to withstand wind loads in open areas. Once the footing is prepared, the post is set plumb and braced until the concrete cures. Panels then slide or fasten into the two integrated channels, locking the system square and keeping alignment consistent over the full run. The eight-foot length allows for adequate burial depth while still leaving sufficient height above grade for six-foot fences with caps. For custom heights, the post can be cut cleanly with a non-ferrous blade, and a flat aluminum cap should always be installed to prevent moisture and debris from entering.
Durability & Maintenance
Aluminum outperforms steel and wood for longevity because it will not rust, rot, or warp. The powder-coat finish ensures the post maintains its deep black color even after years of sun and rain. Maintenance is minimal: rinse with mild soap and water during routine fence cleaning, and inspect posts near gates once or twice a year for movement. Unlike wood posts, there is no staining or sealing required, and unlike steel, there is no risk of rust bleed that can stain nearby concrete or pavers. With proper installation, this post will hold alignment and appearance for decades.
Compatibility
This post is designed to work with systems built on a 2.75″ square profile and requiring two active panel connections. It is best paired with other posts in the same series, including corner, end, and gate posts, to maintain consistent sight lines and performance across the project. For a complete installation, don’t forget to include matching 2.75″ flat aluminum post caps, brackets, and hardware. Keeping all components from the same system ensures a seamless finish and prevents issues with sizing or fit.
Pair With
To achieve a cohesive and professional fence installation, pair the 2.75″ 2-Way Aluminum Post with our full line of aluminum fence kits, driveway gate frames, and flat aluminum post caps. Matching finishes across posts, panels, and gates ensure the system looks intentional and high-end. For contemporary projects, combine this post with aluminum wall cladding to carry the same architectural style across the entire property.
FAQs
Will this post fit any 2.75″ system?
Yes, it is engineered for true 2.75″ (2-3/4″) square aluminum posts with two active panel channels. Always measure your system before ordering.
Why choose aluminum instead of steel?
Aluminum is lighter, easier to install, and will never rust. The powder-coated finish ensures long-term durability without repainting.
Is eight feet long enough?
For most residential and light commercial runs, eight feet provides the right balance between burial depth and above-grade height. In extreme wind zones, check local codes for footing depth and spacing.
Can I cut the post to a shorter height?
Yes, the post can be cut with a non-ferrous saw blade. Be sure to deburr the edge and seal the post with a cap after cutting.
Does the post include a cap?
No. Caps are sold separately. We recommend using the matching 2.75″ flat aluminum cap in black to finish the post and protect it from moisture.
How many posts will I need for my project?
Count one line post for every fence panel section in a straight run, plus additional corner, end, or gate posts as required. Always order a few extras to cover unexpected adjustments or replacements.
