About This

Long-Lasting Durability: This stair cable railing post is made of 1.35mm T304 stainless steel with an upgraded matte black powder coating. Corrosion- and weather-resistant, it’s a low-maintenance solution for stairway on decks, terraces, and balconies. Rubber grommets provide extra protection.

Build Modern Style: Create a sleek, minimalist railing system with this 33°-drilled post, pre-drilled with 10 pairs of holes for smooth cable runs. Designed for stairs with 28°–38° angles, it works indoors or outdoors. Pair with other Zylorix cable railing kits (sold separately) to design a secure, modern deck railing
Safety Compliance: 10 pre-drilled post holes are spaced 3.15" apart to pass the 4" sphere test and comply with residential building requirements. The recommended maximum post spacing is 4 ft (center-to-center), with a maximum cable run of 20 ft per section (up to 6 posts). For straight runs or 90° corner runs over 20 ft, we recommend using our T-corner post or installing the fixed-end terminals(search B0DZH5R72Z) on a single post to reduce cost and maintain a seamless, consistent visual layout
Simplify DIY Installation: The adjustable top bracket easily connects to your handrail, while all mounting screws, foot cover, and rubber grommets are included. Even DIY beginners can install a sturdy, modern railing on decks, terraces, gardens, or stairs with minimal effort
