Can this railing be used in coastal areas?

T304 stainless steel railing is suitable for most outdoor areas. For homes within 10 miles of the coast or high-salt areas, we recommend T316 stainless steel, as T304 may experience oxidation when exposed to salt air.

Why does Zylorix use crimping tensioners instead of other swageless fittings with set screws?

Zylorix crimping tensioners provide a safer (permanent fix), more efficient (only two crimps required), and lower-maintenance solution compared to set-screw swageless fittings, which are susceptible to loosening and require frequent inspections.

The maximum cable length is 20 ft per run per building code. How can I build a railing longer than 20 ft?

For runs over 20 ft (e.g., 40 ft = 20 ft + 20 ft), a standard setup requires 12 posts. You can also search ASIN B0FCYG4FRY to buy an invisible terminal for the 6th post, which connects sections 1 and 2 and reduces the total posts to 11.

Why a max of 4 feet spacing between posts, instead of 5 feet?

1. Designed to meet all building codes to ensure your safety and prevent falls.

2. Closer post spacing provides better load-bearing and stability. While some suggest 5ft spacing for cost savings, we prioritize safety and code compliance for you.

If I have installation issues or receive a damaged or missing item, do I need to return the package?

No, you don’t need to return the entire package. Just email ours about the issue to get the necessary parts resent. We offer unconditional replacements within 365 days.
