A glass railing is a system of parts working together: the glass infill, the mounting hardware that holds it (spigots, standoffs, base shoe, or clamps), the posts and top rail where used, and the smaller fixings and seals that make it work on the real structure. Understanding what each component does makes it easier to spec a complete system and avoid ordering a pile of parts that do not add up to a working railing.
JIT Homes supplies glass railing hardware for project teams. This guide explains the components so you can read a hardware schedule and spec a full system, not just the headline parts.
Glass infill
The panels themselves. This is the structural element in a frameless system, so the glass type, thickness, and make-up are specified to the loads and code, not chosen by look alone. See the Glass Railing Thickness guide.
Mounting hardware
How the glass is held is the defining part of the system. The main options:
- Spigots. Posts or buttons that clamp the base of the glass and anchor to the structure. They give a minimal, floating look.
- Standoffs. Fittings that bolt through the glass to a face or fascia, so the panel reads as a floating plane.
- Base shoe (U-channel). A continuous aluminium channel that runs the length of the run and holds the glass along its base, hiding all fixings.
- Clamps. Brackets that grip the glass edge and mount to posts, used in post-and-clamp systems.
For a deeper comparison of two of the most common base options, see Spigot vs Standoff.
Posts and top rail
Not every system uses them, but where present they share the load and change the look:
- Posts. Vertical supports that carry clamps or hold panels between them.
- Top rail or handrail. A capping rail along the top edge. In many Canadian configurations a top rail is required so the guard stays in place if a panel fails. It also provides a graspable handrail on stairs.
Fixings and anchors
The parts that tie the system to the structure:
- Anchors and bolts sized to the substrate (concrete, steel, timber).
- Base plates or embeds for spigots and posts.
- Through-bolt fixings for standoffs.
These are specified to the substrate and the engineering, which is why the fixing schedule matters as much as the visible hardware.
Gaskets, setting blocks and infill
The small parts that make the glass sit correctly and stay put:
- Gaskets and wedges that grip and cushion the glass in a base shoe or fitting.
- Setting blocks that position the glass and stop it resting directly on metal.
- Structural infill or grout used in some base shoe systems to lock the glass in the channel.
These are easy to forget on a schedule and essential to a working install.
Seals, caps and trims
The finishing parts:
- End caps that close the ends of a base shoe or top rail.
- Cover trims or cladding that hide a base shoe for a clean finish.
- Weather seals where water management matters on exterior runs.
Reading a hardware schedule
A complete schedule covers all of the above for the whole run: glass panels, mounting hardware, posts and top rail where used, fixings sized to the substrate, gaskets and setting blocks, and caps and trims. If a quote only lists the glass and the spigots, it is not yet a complete system. Use the component list to check nothing is missing before you order.
Frequently asked questions
What are the main parts of a glass railing? Glass infill, mounting hardware (spigots, standoffs, base shoe, or clamps), posts and top rail where used, and the fixings, gaskets, setting blocks, and caps that complete the system.
Do I always need a top rail? Not always, but many Canadian configurations require one so the guard stays in place if a panel fails, and stairs usually need a graspable handrail.
What holds the glass in a base shoe system? Gaskets and wedges, and in some systems a structural infill or grout, hold the glass in the continuous channel.
Why does the fixing schedule matter so much? Because the anchors and fixings are what tie the guard to the structure and are sized to the substrate and engineering. The visible hardware is only part of the system.
