Internal Structural Post by Deckorators
What It Is
The Internal Structural Post from Deckorators is a purpose-built load-bearing post support designed to replace a traditional 4″ x 4″ wood post underneath a deck railing sleeve. It provides a strong, stable core that your railing can be anchored to — without needing a solid wood post inside the decorative sleeve.
Key Features
- Aluminum Construction: The internal post is made from aluminum, which resists rot and corrosion better than wood — great for outdoor use.
- Adjustable Height: Ranges from about 36″– 42″ in usable length, so it fits most standard deck railing heights.
- Designed for Sleeves: It’s meant to be wrapped with a post sleeve (like a vinyl or composite sleeve) so the finished appearance matches your deck design.
- Code Compliance: Built to meet relevant building code requirements for deck railings when installed per instructions.
- Lifetime Limited Warranty: Deckorators backs the product with a warranty, giving some protection against manufacturing defects.
What’s Included
A typical kit includes:
- The structural aluminum post - 1
- Post leveling shims - 2
- Extrusions to center it inside a 4×4 sleeve - 2
- Centering screw and leveling shims - 1
(Mounting hardware to secure to the deck framing or surface mount may be included or sold separately depending on the exact SKU.)
How It’s Used
- Support for Railing: This post acts as the structural backbone for a railing system. It transfers load from the railing into your deck frame or surface below.
- Sleeved Finish: You slide a decorative sleeve (vinyl, composite, etc.) over it to get a finished look that matches your deck aesthetics.
- Versatile Mounting: Can be installed on wooden deck framing or adapted for surface mounts with the right hardware.

About this product…
The Internal Structural Posts by Deckorators are a cost-effective, easeful option for homeowners intending to wrap their posts with post sleeves. Wrapped around the steel structural posts are multiple points of vinyl excursion centers, which support the prospective post sleeve or newel. These excursions create greater stability and load bearing capacity by transferring the load placed on the railing to the structure below the deck surface. These posts can be mounted to either the deck frame or a surface mount. Along with sustainability, these posts are adjustable in length, ranging from 36” - 42”, allowing the customer flexibility and choice when customizing their outdoor area.
