Base glass clamp

The Strofix base glass clamp (bottom round) is an AISI 304 stainless-steel floor-mounted spigot with a Ø48 mm round profile, designed to hold 12–17.52 mm glass panels vertically in frameless glass railing and balustrade systems. Overall height is 182 mm. Available in two colour options: matte or silver. The matte option provides an anthracite-toned finish; the silver option retains the natural stainless-steel satin appearance.

The base glass clamp is anchored to the floor or structural slab and grips the glass panel from below, holding it in a vertical position without the need for railing posts. The 12–17.52 mm glass thickness range covers standard toughened glass and common laminated safety glass buildups used in glass balustrade applications. The Ø48 mm round body provides a clean, cylindrical profile at the base of the glass panel. AISI 304 stainless steel is suitable for standard interior and exterior installations.

This is the bottom-mount, round-profile variant. The Strofix Spigot System range also includes bottom-mount square and side-mount variants for different mounting positions and post profile preferences.

Use cases:

• Frameless glass balustrades on balconies, terraces, and rooftop decks
• Floor-mounted glass railing systems for residential and commercial buildings
• Pool fencing and wet-area glass barriers with base-mounted spigots
• Staircase glass balustrades without metal post supports
• Mezzanine and gallery edge protection with frameless glass panels
• Shopfront and reception area glass partitions with visible base clamps

FAQ:

What glass thickness does this clamp accept?

The base glass clamp accepts glass panels from 12 to 17.52 mm thick. This range covers standard toughened glass and common laminated safety glass buildups used in glass balustrade systems.

What do the matte and silver colour options mean?

The matte option provides an anthracite-toned coated finish. The silver option retains the natural stainless-steel satin appearance. Both use the same AISI 304 stainless-steel body. Select the colour in the dropdown at order time.

What is the overall height of the clamp?

The clamp has an overall height of 182 mm (H = 182 mm). This is the total vertical dimension from the mounting surface to the top of the clamp body.

How is this clamp mounted?

The base glass clamp is mounted to the floor or structural slab from below — hence "bottom" in the product name. The clamp is anchored to the substrate and the glass panel is inserted into the clamp channel and secured.

What is the body diameter?

The clamp has a Ø48 mm round cylindrical body. This is the "round" variant in the Strofix Spigot System range. A square-profile variant is also available.

What other base glass clamp variants does Strofix offer?

The Strofix Spigot System range includes four base glass clamp types: bottom round (this product), bottom square, side round, and side square. "Bottom" and "side" refer to the mounting position; "round" and "square" refer to the body profile shape.

About Spigot Systems

A spigot system is a base-mounted glass clamp that grips a glass panel along its bottom or side edge, anchoring the panel directly to a floor, deck or fascia without the need for vertical posts.

The result is a frameless glass balustrade where the glass itself forms the barrier and no intermediate posts interrupt the sightline.

Each spigot clamp consists of a solid base that bolts to the substrate and a clamping channel that holds the glass securely with internal pressure.

Strofix supplies base glass clamps in four configurations: bottom-mount round (Ø48 mm), bottom-mount square (50×50 mm), side-mount square (40×40 mm) and side-mount round (Ø42.4 mm) — all in AISI 304 stainless steel, with satin or matte black finishes.

The correct spigot depends on mounting orientation (bottom or side), base profile (round or square) and the desired finish.
