A complete structural kit featuring 180° foldable swivel ends for stairs and adjustable threaded tensioners. Includes all necessary nuts, washers, and decorative caps. Finished in durable Black PVD.

Overview

Build a professional railing with the RiaYer Black Adjustable Turnbuckle System. This kit is engineered with a 180° Foldable Swivel Joint that automatically adapts to any angle, making it perfect for complex staircases and deck transitions.

Key to its design is the Adjustable Thread Mechanism. By rotating the body, you can extend or retract the threaded length to create precise tension on the wire rope. Each set comes fully equipped with hex nuts, washers, and acorn caps for a secure and clean installation.

Why Choose This Adjustable Kit?

• 📐 180° Foldable Swivel (Universal Angle): The end fittings feature an articulated joint ("foldable" design) that swivels 0-180°. It eliminates the need for angled washers, as the hardware naturally aligns with the slope of your stairs or the level of your deck.
• ⚙️ Adjustable Thread Length (High Tension): The system features a long threaded range. By rotating the turnbuckle body or adjusting the nuts, you can significantly change the length of the hardware. This "Travel" allows you to pull the cable extremely tight and re-tension it easily in the future.
• 🔩 Complete Hardware Set (Nuts & Caps): We include everything you need for a finished look. The kit comes with Hex Nuts (for locking), Washers (for surface protection), and Acorn/Cap Nuts (to cover the threaded end for safety and aesthetics).
• 💎 Black Titanium PVD Finish: Crafted from Marine Grade T316 Stainless Steel with Vacuum Titanium Plating. It offers a stunning matte black look that is integral to the steel—scratch-resistant, rust-proof, and peel-free.

How to Install:

1. Drill & Mount: Drill pilot holes and mount the swivel bases to your posts.
2. Crimp: Insert the wire rope into the swage stud. Use a Hydraulic Crimper to crimp the tube securely.
3. Connect: Attach the crimped stud to the mounted swivel base. Assemble the washers and nuts.
4. Tension (Adjust Thread): Rotate the turnbuckle body (or tighten the nut, depending on model). This utilizes the Adjustable Thread Length to draw the wire tight.

FAQ

Q: How does the "Adjustable Thread" work?
A: The hardware has a threaded section that can move in or out. By rotating it, you shorten the overall length of the fitting, which pulls the wire rope tight (tensions it). This allows for easy re-tightening if the cable slackens over time.

Q: What are the nuts and caps for?
A: The Hex Nuts lock your tension setting in place so it doesn't loosen. The Cap Nuts (Acorn Nuts) screw onto the end to cover sharp threads, preventing snagging and giving a polished black look.

Q: Is the 180° fold meant for stairs?
A: Yes. The "foldable" or swivel joint allows the fitting to bend freely, aligning perfectly with the angle of your staircase railing without bending the wire.
