Post-less corners, how they work and how they support the balustrade structure.

One of the unique features of the Balconette Systems’ design is the ability to have postless corners.

Postless corner, inside and out.

  • The structure works because one side resists the forces of the other.
  • The handrail is fixed at each end. So we have one handrail fixed at one end, an angled corner, and the other handrail fixed at the other end.
  • The glass is fixed with silicone sealant. The bottom and top of the glass are fixed all the way along, to the bottom rail and the hand rail, with a continuous bead of silicone sealant.

The glass and rail make a single rigid corner

When the handrail on one side is pushed, it is restrained by the other side. Therefore when the handrail is pushed outwards, then the other side wants to stretch. But it can’t because it’s restrained by the glass and rail making a single rigid corner.


Similarly, when this handrail is pushed out, it is held by the strength of the other side. That’s why we don’t need a corner post – in fact, it’s considered stronger than a post.

Balustrade corner is as strong as a wall fixing

Glass balustrade corner is as strong as a wall fixing, so the rail can span the maximum length on both sides, counting the corner as a wall connection. Therefore when we’re stating the maximum length the handrail can be without posts, we consider a corner the same as a wall fixing, so the rail can span the maximum length on both sides, counting the corner as if it were a wall connection.

And that’s how Balconette balustrades work without needing a post at every corner.
