When planning a glass railing system with spigots, one of the most common questions is how many spigots are needed for each glass panel. The answer depends on the panel size, glass specification, railing height, and project requirements.

Spigot Spacing Depends on the Glass Panel

Spigots support the glass panel from the bottom, so their spacing should be considered together with the glass size and installation conditions.

A larger glass panel may require a different support arrangement from a smaller panel. The substrate and the expected loads should also be considered before determining the final spacing.

For this reason, there is no single spigot spacing that is suitable for every glass railing project.

Glass Thickness Matters

The glass thickness and configuration should be confirmed before deciding the support layout.

Tempered glass and laminated tempered glass can have different structural characteristics, and the glass specification should match the selected spigot system and project requirements.

What About SG20?

Our SG20 Stainless Steel Glass Spigot is designed for frameless glass railing applications including balconies, decks, staircases, pool fencing and other outdoor areas.

It is available in SS304 and SS316 stainless steel and can be used with different safety glass configurations.

For coastal or high-humidity projects, SS316 is generally preferred for its higher corrosion resistance.

How to Confirm the Right Number of Spigots

Before ordering, prepare the following information:

• Glass panel width and height
• Glass thickness and configuration
• Total railing length
• Installation location
• Substrate type
• Project location

With these details, the railing supplier can recommend a suitable spigot arrangement and provide a more accurate quotation.

The number of spigots should always be confirmed as part of the complete glass railing system rather than calculated from panel width alone.
