A post-free glass railing has no visible posts between the glass panels, while a glass railing with posts supports the glass using posts and hardware. A post-free design offers a more unobstructed view and a cleaner, more minimalist look, while posts provide more opportunities to combine materials and details.
In a post-free railing, the glass is held in place by a sturdy bottom profile, which places higher demands on the mounting surface and requires thicker glass—which is why it’s more expensive. With posts, the posts themselves, their color, and the crossbars can become part of the design. A post-free railing is best when the view is the most important factor, while posts offer greater freedom in terms of materials and design.
