Railing Anatomy
Click on the hot spots below to explore the core components of a railing system.
Post Sleeve
A post sleeve is a durable covering designed to protect your railing posts and enhance your deck's style. Available in composite 4x4 or 6x6 sizes and a variety of colours, it pairs perfectly for a low-maintenance, long-lasting finish. Alternatively, you can use an aluminium 4x4 post sleeve an aluminium post for a sleek and sturdy design.
Post Cap
A post cap adds the finishing touch to your deck posts, offering both protection and style. Choose our traditional post cap or upgrade to a lighted post cap for added ambiance and visibility—perfect for elevating your railing with elegance and functionality.
Post Skirt
A post skirt conceals gaps around the base of deck posts, providing a more finished look. Select our durable, easy-to-install post skirts to eliminate unsightly gaps, enhance the look of your railing, and protect against moisture.
Balusters
Balusters provide support and style to your railing. Choose square composite for a classic look or round aluminium for modern flair. Both options offer strength and low maintenance, ensuring your railing is both beautiful and durable.
Top Rail
The top rail is the uppermost piece of the railing, offering grip and stability. Opt for our smooth, durable crown top rail for a comfortable handhold or upgrade to a cocktail rail for a stylish and convenient ledge for drinks.
Bottom Rail
A bottom rail provides foundational support to your railing structure. Engineered for durability, it complements your top rail, ensuring your composite railing system is robust and secure.

*Trex decking with heat mitigating technology can still get hot to the touch when direct sunlight and high temperatures converge for extended periods of time. We therefore recommend shoes, socks, and pet booties, so that you and yours can enjoy living on your deck as much as we’ve enjoyed innovating it.
