Glass Balustrade Hardware: Spigots, Clamps and Base Shoes Explained

t327-38

Glass balustrade hardware is the set of metal fittings that hold glass panels on a stair or balcony railing. Spigots, clamps and base shoes each secure the glass in a different way, and choosing the right type and finish affects both safety and appearance. A correct fitting plan starts with the glass thickness, the railing layout and the load the railing must carry.

What Glass Balustrade Hardware Includes

Glass balustrade hardware covers every metal part that connects the glass infill to the structure. The main components are spigots, which are round or square fixing points that grip the glass edge, clamps that hold the panel from the side, and base shoes, which run along the bottom of the glass on a stair or floor.

Each component has a specific role. Together they transfer the forces from the glass to the stair or balcony structure, so every part should be matched to the others rather than chosen separately.

Spigots: Point Fixings for Glass Panels

Spigots are small fixings that attach to the glass with a cylindrical or flat body, usually through a drilled hole. They are popular for a minimal look because only a few points are visible on the glass surface.

Suitable for frameless or semi-frameless designs
Require drilled glass, prepared to exact positions
Often used on stair landings and balcony edges

Spigot positions and hole sizes must be coordinated with the glass supplier before cutting.

Clamps: Side Support for Glass Infill

Clamps grip the glass edge without drilling, using a bracket that tightens around the panel. They are a practical choice when drilling is not desired or when the glass is already tempered and cannot be modified.

Clamps come in several forms, including top-mounted and side-mounted designs. The choice depends on the handrail profile, the spacing of posts and the visual style of the railing.

Base Shoes: Securing the Bottom of the Glass

A base shoe is a channel fixed to the floor or stair tread that holds the bottom edge of the glass panel. It keeps the glass aligned and absorbs small movements, which is why it is common on stairs and balconies with glass infill.

Base shoes are usually paired with a gasket or sealant that protects the glass edge and reduces rattling. The channel should be level and properly anchored, since it carries part of the load from the panel.

Finishes and Materials to Consider

Hardware is commonly produced in stainless steel, aluminum or steel with a protective coating. The finish affects corrosion resistance, especially near the sea, and the final look of the railing.

Brushed or polished stainless steel for a modern appearance
Powder-coated steel in matching colors for a uniform look
Hot-dip galvanized steel for strong corrosion protection before coating

Choose the finish together with the rest of the metalwork so that colors and materials match.

Choosing and Installing the Right Fittings

Start by confirming the glass thickness, type and whether it is tempered or laminated. Next, check the railing height, post spacing and the expected loads on the balustrade. These details determine the fitting type and the number of attachment points.

Installation should follow the manufacturer's drawings and an engineer's guidance. Exact load values and standard requirements, including the Israeli railing standard SI 1142, should be verified with the structural engineer on your project.

Frequently asked questions

What is the difference between a spigot and a clamp?

A spigot fixes to the glass through a drilled hole, while a clamp grips the glass edge without drilling. Spigots give a cleaner look, and clamps suit projects where the glass cannot be drilled.

Do I always need a base shoe on a glass stair railing?

Not always, but a base shoe is common on stairs and balconies because it locks the bottom of the glass in place. Your design and engineer will confirm whether it is needed for your project.

Which finish is best for hardware near the sea?

Stainless steel and properly galvanized and coated steel both resist corrosion well. Discuss your location with the manufacturer so the finish suits the exposure.

Can glass balustrade hardware be fitted to existing glass?

It depends on whether the glass can be drilled or whether clamp-type fittings can be used. Measure on site and consult the glass supplier before making any changes.

Common mistakes to avoid

A common mistake is ordering hardware before confirming the glass thickness and type, which can lead to fittings that do not fit. Another is mixing metals or finishes without checking compatibility, which can cause corrosion and an uneven look.

Our recommendation

Measure the glass and the structure on site, then choose spigots or clamps based on whether drilling is acceptable. Ask for a written drawing that shows fitting positions before production starts.

Summary

Spigots, clamps and base shoes each secure glass balustrades in their own way, and the right choice depends on glass type, layout and finish. Plan the hardware together with the glass and confirm details with an engineer.
