⚙️ Why Metal Railings + Witop® Decking Win
| Traditional Mounting | Witop® SnapRail™ System |
|---|---|

🔧 Step-by-Step Installation Guide
1. Planning & Safety Prep
- Check Codes: 36″ min. height • 4″ max. gap between balusters
- Mark Layout: Use Witop® PostPlanner™ laser tool for perfect spacing
- Avoid Drilling: Never penetrate composite boards (voids warranty)
2. Install Anchors
Witop® BaseLock™ Anchors:
- Mount steel foot plates directly to deck joists
- Slide waterproof gasket over plate
- Insert powder-coated post → tighten set screws
3. Attach Top Rail
- SnapRail™ Tech:
- Place rail on posts
- Slide invisible clamps up from underside
- Twist 90° → locks with click
- Pro Tip: Use Witop® TruLevel™ caps for slope adjustment
4. Add Balusters
Witop® SpeedBaluster™ Kit:
- Pre-spaced cables/glass/iron rods
- No-Weld Clamps:
- Top: Slide into rail channel
- Bottom: Snap onto anchor plate
- Gap Check: Verify ≤4″ spacing
5. Seal & Secure
- Apply MarineGuard™ Sealant around base
- Install post caps with UV-resistant adhesive
- Conduct 250kg load test per post
