Specialized protection for staircases. These angled sleeves prevent wire rope from cutting into wood posts on sloped runs. Available in 30° and 45° angles. Marine Grade T316.

Overview

Drilling angled holes for stair railings can be tricky, and without protection, the cable will quickly dig into the wood. RiaYer Angled Protective Sleeves are the professional solution. Designed with a precise flange angle, they sit flush against your stair posts, guiding the cable smoothly through the wood.

Crafted from T316 Marine Grade Stainless Steel, these sleeves are available in two angle options (30° and 45°) and two premium finishes (Classic Silver & Black Titanium PVD) to match your entire railing system.

Why Choose These Angled Sleeves?

• 📐 Precise Angle Options (30° & 45°): Unlike generic sleeves, these are pre-angled. The 30° model fits stair angles between 25°-35°, while the 45° model is designed for steeper slopes. This ensures a tight, flush fit on the post surface.
• 💎 Premium Black Titanium Plating: For the black version, we use advanced PVD Titanium technology combined with a safety coating. This creates a hard, glossy black finish that resists wear, corrosion, and fading far better than standard paint.
• 🛡️ Protects Wood Posts: On staircases, the tension force is diagonal. These sleeves absorb that force, preventing the 1/8" cable from "sawing" into the wood post, which is crucial for maintaining tension over time.
• ✨ Invisible Elegance: With a compact flange design, these sleeves cover the rough edges of your angled drill holes, leaving a clean, polished look that blends seamlessly into the post.
• 🌊 T316 Marine Grade: Built for the elements. Whether you choose Silver or Black, the core material is T316 stainless steel, offering superior rust resistance for indoor and outdoor use.

How to Install:

1. Measure: Determine the angle of your staircase to choose the correct sleeve (30° or 45°).
2. Drill: Drill a 1/4" hole through your wood post at the same angle as your stairs.
3. Insert: Tap the angled sleeve into the hole. Rotate it until the angled flange sits perfectly flush against the wood surface.
4. Run Cable: Pass the 1/8" wire rope through. The sleeve will now handle the friction.

FAQ

Q: My stairs are 32 degrees. Which one should I choose?
A: Choose the 30° model. It is designed to accommodate a range of angles from approximately 25° to 35° comfortably.

Q: Will the Black Titanium coating fade?
A: No. We use advanced Titanium PVD plating technology. It increases surface hardness and wear resistance, ensuring the black finish stays pristine even under cable tension.

Q: Do I need these for every post on the stairs?
A: We recommend using them on all intermediate wood posts to prevent the cable from cutting a groove into the wood, which creates slack in your system.

Q: Are they visible after installation?
A: Barely. The flange is small (0.54") and designed to look like a neat grommet, blending seamlessly into your railing design.
