Keylink Aluminum Railing Posts are designed to provide a strong, reliable foundation for standard aluminum railing systems using infill options like square balusters or pickets. Constructed from heavy-duty aluminum with a durable powder-coated finish, these posts are built to resist corrosion, fading, and harsh outdoor conditions, making them ideal for decks, porches, and balconies. Their clean, square profile delivers a modern appearance while maintaining the structural integrity required for long-term residential use. Many models include a welded base plate with a leveling system, allowing for precise, plumb installation without shimming and helping ensure a consistent, professional finish.
Available in multiple configurations—including line, end, and corner posts—these posts integrate seamlessly with railing systems such as the American and Chesapeake Series. Offered in common residential heights like 38", 44", and 48", they are designed to meet standard code requirements and pair with a variety of brackets, trims, and caps (sold separately) to complete the system. With low-maintenance performance and durable construction, Keylink aluminum posts provide a dependable solution for building cohesive, long-lasting railing systems.
