Stainless Steel 90 Degree Square Glass to Glass Railing Clamp Corner Glass Stiffener for Frameless Glass Railing

It is built for 8-12 mm tempered and laminated glass - both types fit the same clamp because the jaws grip the edge rather than the face. That covers the common frameless railing panels. If your panel falls outside 8-12 mm, tell us before ordering; the jaw or gasket set would need adjusting.

Fixed 90 degrees is the right choice for square corners, typical of most stair landings and balcony returns - it is stiffer and cheaper. The adjustable version is for corners that are not exactly 90 degrees, like curved balconies or angled stair layouts. If the corner angle is unknown or likely to vary on site, the adjustable version takes that tolerance.

It ties two glass panels together at the corner so they work as one rigid structure instead of two independent edges. That matters at a free corner - without it the panel edges move separately and the corner becomes the weak point under hand load. The 90-degree tie-in also keeps the corner gap even, so the silicone line stays straight.

Yes - the clamp wraps the corner with jaws on both panel edges, and the bolts tension both sides together. That means the two panels are clamped to each other, not just held individually - which is exactly what makes the corner stiff. Both glass edges get the rubber cushion, so there is no metal contact.

The clamp is designed glass-to-glass at a 90-degree corner. Where a panel terminates at a wall or post, you use the wall-mount or post-mount clamp instead - that is a different jaw layout. If your layout has one glass corner and one wall end, the order is typically a 90-degree corner clamp plus a wall or post clamp for the other end.

Brushed nickel, chrome, matte black and custom colors, in 304 or 316. The clamp usually sits at eye level at stair corners, so finish matching matters - order it with the rest of the hardware in one batch and the tone stays consistent. For a coastal balustrade, 316 is recommended for the corner clamp since corners trap water in the jaw area.
