An adjustable glass spigot (base mount) is a key hardware component used in frameless glass pool fencing systems. It anchors tempered glass panels securely to a surface (typically concrete or decking) while allowing fine adjustments for alignment.

🔧 What It Is

A base-mounted adjustable spigot:

• Is surface-mounted (top mount) onto a slab or deck

• Holds glass panels using a friction-fit system (no holes in glass)

• Includes adjustment screws or tilt mechanisms to level panels on uneven surfaces

🛠️ Key Features

• Material: Usually duplex 2205 stainless steel (marine-grade, highly corrosion-resistant)

• Glass thickness compatibility: Typically 10mm–17.52mm tempered glass

• Adjustment capability:

  • Tilt adjustment (~5–7°)

  • Height adjustment (~10–12mm)

• Mounting: 3–4 anchor bolts into concrete or structural surface

• Finish options: Satin, mirror, black, powder-coated

🧱 Installation Basics

• Mounted directly on:

  • Concrete slabs (most common)

  • Wood decks (with proper reinforcement)

• Requires:

  • Anchor bolts (often M10/M12 stainless)

  • Base plate cover (for clean finish)

• Typical spacing:

  • 2 spigots per 4 ft (≈1.2 m) glass panel

👍 Advantages

• Clean frameless look (minimal hardware visible)

• No drilling into glass required

• Adjustable → ideal for slightly uneven slabs

• Strong and durable for outdoor / pool environments

⚠️ Things to Watch

• Surface must be structurally solid and level (or within adjustment range)

• Poor anchoring can lead to movement (especially under load)

• Not ideal for heavily sloped surfaces → core-drilled spigots may be better

💡 Pro Tip (from real installs)

If your slab isn’t perfectly level:

• Adjustable spigots help—but only within limits

• For large slopes, consider:

  • Grinding slab

  • Using shims/grout

  • Or switching to core-drilled spigots for better stability
