Glass clamp 45x45mm, Flat, Satin, With support

The Strofix glass clamp 45×45 mm flat with support is a stainless-steel glass panel holder designed for mounting on flat surfaces such as walls, square posts, and flat-sided structural members. The clamp measures 45 × 45 × 26 mm (L × H × depth) and holds glass panels from 6 to 10.76 mm thick. The distance between the mounting surface and the glass panel is 20 mm. Available in AISI 304 or AISI 316 with a satin finish. Attached by screwing (elements for screwing included).

The "with support" version includes a security plate and safety pin — a small metal bracket that sits underneath the glass panel, providing a secondary mechanical safety catch in addition to the rubber gasket clamping force. If the clamping pressure were ever to fail, the safety pin prevents the glass panel from dropping out of the clamp. This support feature may be required by building codes for glass balustrade installations where the glass panel is at height and a panel drop would pose a safety risk. The set also enables side-mounting to posts. Glass thickness options cover single tempered glass (6, 8, 10 mm) and laminated safety glass (8.76, 10.76 mm). AISI 304 is suitable for standard installations; AISI 316 provides higher chloride resistance for coastal or exposed environments.

Select the glass thickness and steel grade in the dropdowns at order time.

Use cases:

• Glass balustrade panels requiring safety support as specified by building codes
• Flat-mount glass clamp installations where a secondary glass retention mechanism is needed
• Side-mounting glass panels to square railing posts with the included security plate
• Balcony and terrace glass railings at height where panel drop prevention is critical
• Coastal installations requiring AISI 316 glass clamps with safety support

FAQ

What does "with support" mean?

The "with support" version includes a security plate and safety pin that sit underneath the glass panel, providing a secondary mechanical safety catch. This prevents the glass from dropping out of the clamp if the primary clamping force is disrupted. The "without supporter" version (SKU ST-045450) relies on clamping pressure alone.

How does this compare to the version without support?

Both clamps are 45 × 45 mm flat satin with the same glass range, grades, and 20 mm standoff. The difference is the included security plate and safety pin. The "with support" version costs approximately €1.44 more per clamp. Choose "with support" when building codes require a secondary glass retention mechanism or when the installation is at height.

What glass thicknesses are supported?

The clamp accepts glass from 6 to 10.76 mm: single tempered glass (6, 8, 10 mm) and laminated safety glass (8.76, 10.76 mm). Select the matching rubber gasket in the dropdown.

Can this be side-mounted to posts?

Yes. The description notes that side-mounting to posts is possible using the included security plate. This enables the clamp to be attached to the side face of a railing post rather than the front face.

Which steel grades are available?

AISI 304 and AISI 316. Choose AISI 316 for coastal, pool, or high-humidity installations.

How is the clamp attached?

The clamp is attached to the mounting surface by screwing. Fastening hardware is included.

About Glass Clamps for Flat Surfaces

A glass clamp for a flat surface is a stainless-steel bracket that grips a glass panel along its edge without requiring a drilled hole, fixing the panel to a wall, post or flat-sided structure by clamping pressure alone. Two halves tighten around the glass with rubber inserts that cushion the contact and accommodate different panel thicknesses.

Strofix supplies flat-mount glass clamps in ten body variants — from a compact 30×30 mm mini clamp to larger bodies with lengths up to 67 mm, heights up to 45 mm and glass-edge overhangs up to 18 mm — in AISI 304 or AISI 316 stainless steel with satin or polished finishes. Rubber inserts are available for 4, 6 and 8 mm glass, or the clamps can be ordered without rubbers for custom applications.

The correct clamp depends on body size, glass thickness, steel grade and the required finish.
