The robust choice for metal and wood posts. This 6-inch through-post tensioner kit features our premium Black Titanium PVD finish, offering industrial strength with a sleek, fade-proof aesthetic.


Product Overview

Build a rock-solid railing with the RiaYer Black Titanium 6-Inch Threaded Stud System. Designed to pass completely through standard 2"x2" metal posts up to thick 4"x4" wood posts, this kit works by tensioning the cable from the backside of the post. It’s the preferred choice for professional contractors needing maximum tension control and structural integrity.

Why Choose This Kit?

  • 💎 Black Titanium PVD Technology: We use advanced Vacuum Titanium Plating to bond the black finish to the T316 steel. Unlike standard spray paint, this metallic finish is ultra-hard, scratch-resistant, and will not peel or fade under the hot sun.
  • 🌿 Safe & Eco-Friendly: Finished with a specialized protective coating that is non-toxic and environmentally safe (food-grade standard), making it ideal for family homes with children and pets.
  • ✂️ Versatile "Cut-to-Fit" 6-Inch Design: The extra-long 6-inch threaded stud provides massive adjustability. It easily spans thick end-posts. Simply cut off the excess thread with a hacksaw after tensioning for a custom, clean flush fit.
  • 🔄 Multi-Angle Ready: Perfect for both level decks and staircases. (Note: For angled stair installations, use our 30° Beveled Washers to ensure the nut sits flush against the angled post).

Frequently Asked Questions

Q: Will the Black Titanium coating fade?

A: No. The PVD (Physical Vapor Deposition) process creates a surface harder than the steel itself. Combined with our safety coating, it is highly resistant to UV fading and wear, ensuring it stays black for years.

Q: Can I use this on Wood posts?

A: Yes. While widely used for metal posts, it works great on wood posts too. Just ensure you use the included washer to prevent the nut from sinking into the soft wood.

Q: What if the 6-inch stud is too long for my 2" post?

A: That is by design! The long 6" thread allows a single kit to fit all post thicknesses (from 2" metal tubes to 4" wood beams). You simply cut off the extra length after tensioning.

Q: Do I need extra parts for stairs?

A: Yes. Since the stud goes straight through the post, you will need our 30-Degree Angle Beveled Washer to help the flat nut sit flush against the angled post surface on stairs.
