The ultimate rust-free solution for stairs. Combining our patented internal swage technology with a 0-180° adjustable design and a premium Black PVD finish. Perfect for angled wood post installations without exposed hardware.

Overview

Bring the seamless look of invisible railing to your staircase with the RiaYer Black Patented Adjustable Kit. This system features an articulated terminal that pivots from 0 to 180 degrees, allowing it to adapt perfectly to any stair slope or deck angle.

Crafted from T316 Stainless Steel with a luxurious Black Titanium PVD finish, it retains our signature Hidden Crimp Technology, ensuring maximum rust protection by concealing the swage marks inside the hardware for a flawless, modern look.

Why Choose This Adjustable Patented Kit?

• 📐 0-180° Multi-Angle Freedom: Unlike fixed terminals, this adjustable design allows the cable to exit the post at any angle. It is the perfect problem-solver for stair railings, ramps, and non-standard corners.
• 🖤 Premium Black Titanium PVD Finish: Unlike cheap spray paint, our vacuum-plated metallic finish bonds directly to the steel. It is scratch-resistant, peel-proof, and provides a stunning contrast against wood posts.
• 🛡️ Patented Rust-Free Technology: We've solved the #1 cause of cable railing rust. By hiding the crimp marks inside the tube, we protect the steel's passivation layer from salt and moisture. Ideally suited for coastal and outdoor environments.
• 👻 Clean & Minimalist: No bulky turnbuckles or external hinges. The hardware recesses into the wood post, creating a sleek, continuous line that emphasizes your view, not the fittings.
• 🌲 Wood Post Specialist: Engineered with a deep-thread design (Left & Right hand threads) to anchor securely into Wood Posts, ensuring stability even under the tension of angled runs.

FAQ

Q: Will the black color peel off during installation?
A: No. We use PVD (Physical Vapor Deposition) technology. The black color is bonded to the stainless steel surface, ensuring it won't chip or fade even when adjusting the terminal.

Q: Can I use this on flat sections too?
A: Yes. Since it adjusts from 0 to 180 degrees, it works for both flat and angled runs. However, for a strictly flat deck, our straight/fixed version might be a more economical choice.

Q: Why is "Internal Crimp" important for stairs?
A: Stair railings often face more weather exposure. Hiding the crimp ensures that water doesn't pool in the crimp grooves, significantly extending the life of your railing.
