Why Choose BLIKA Railing Posts?
✓Code-Grade Safety

Available in 36" and 42" heights, they meet both residential and commercial railing codes. Laboratory testing has shown that these posts can withstand 200 pounds per square foot of pressure, ensuring that standard cable-filled systems remain stable without the need for additional reinforcement.
✓Coastal-Grade Corrosion Protection
Blika cable railing posts feature a marine-grade T304 stainless steel core with a UV-resistant matte black powder coat, designed to withstand salt, rain, and sun exposure for decades. For inland projects, posts are also available in brushed or anodized aluminum, providing the same rust-resistant performance. Minimal maintenance is required—simply rinse with mild soapy water to keep a lasting, polished look.

How to Choose the Right Cable Railing Posts?
Choosing the right cable railing post starts with understanding your project.
Installing on a Deck or Balcony?
If your railing will be installed on a flat surface, such as a deck, patio, balcony, or porch, level posts are the right choice. Surface mount posts are the most popular option because they install directly onto the deck surface and work well for most projects.
If maximizing floor space and preserving views are priorities, side mount posts offer a sleek alternative by attaching to the outside of the structure rather than the top.
Building a Stair Railing?
Stair railings require posts designed for angled cable runs. Adjustable stair posts allow the top bracket to match the slope of your staircase, creating a clean and professional appearance while simplifying installation.
If your project includes both stairs and level sections, you'll typically need a combination of stair posts and level posts.
Select the Right Post Position
Each cable railing system typically requires several types of posts. Using the correct post type helps maintain proper cable tension and creates a cleaner finished look.
· End Posts – End posts are used at the beginning and end of a cable railing system, where the cable tension is anchored. They are built to handle the highest load because they resist all the pulling force from the tightened cables, ensuring a stable and secure railing structure.
· Intermediate Posts – Intermediate posts are installed between end posts to support the cable runs over longer distances. They help maintain proper spacing and reduce cable deflection or sagging, keeping the system visually straight and structurally consistent.
· Corner Posts – Corner posts are designed for areas where the railing changes direction, such as 90° or angled turns. They allow cables to transition smoothly around corners while maintaining proper tension and alignment throughout the system.
· Stair Posts – Stair posts are specifically engineered for sloped or stepped installations along staircases. They ensure the cables follow the angle of the stairs cleanly, maintaining both safety compliance and a uniform modern appearance.
36” or 42”Height?
Most residential deck cable railing systems use 36" posts, while 42" posts are commonly required for taller guardrails and many commercial applications.
If you're unsure which height is right for your project, check your local code requirements or contact our team for guidance before ordering.
