About This

Swageless, Reusable, Easy-Install Kit: No hydraulic crimping tool required — save $30–$80 instantly. Zylorix patented swageless tensioners stay fully concealed inside the post for a clean, modern look. Optimized 5 cm terminals for level runs and 6 cm for stairs ensure full concealment and maximum adjustment flexibility. Terminals are fully reusable — cut, recut, and reinstall cables without waste. Each terminal is tested to withstand 220 lb tensile force for long-term safety and reliability
Longer Cable Extension, More Budget-Friendly: Our stair railing post kit comes with an extended 219ft cable, allowing it to seamlessly reach the next 3 posts without requiring another full set. Simply add our single posts and pair them with Zylorix black handrails (available in 4–10 ft lengths) to complete your layout — whether for stairs, landings, corners, or long straight runs. This modular design lets you expand flexibly, avoid waste, and complete your project more cost-effectively
Slimmer 1/10" Cable, Clearer View: Upgrade to a 1/10" (2.5 mm) stainless steel black cable for a sleeker, less obstructed view than standard 1/8" wire — while still supporting over 600 lbs of tension to maintain safety and structural strength. Ideal for modern decks, porches, entrances, stair railings indoor and outdoor
Outdoor-Grade Post Kit for Long-Term Use: Built from premium T304/T316 stainless steel, this cable railing post kit ensures superior rust and corrosion resistance. Each 35"x2"x2" post features an upgraded 1.35 mm wall thickness—35% thicker than standard posts—for higher load capacity and stability. The enhanced outdoor-grade matte black powder coating resists fading, and UV exposure, maintaining a refined look and structural strength for 3+ years in harsh weather, except within 10 miles of the coast (Need posts for coastal areas, please search for "Zylorix SS316 cable railing post")
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
